We supply and install MTO-approved steel beam guide rail systems built to the OPSD standard drawings, including OPSD 912.101 and OPSD 912.532, with the mounting height range, splice direction, block type, and reflector spacing the specification calls for.
Steel posts with plastic or routed wood blocks, or wooden breakaway posts with wood blocks, selected to what the drawings specify. We do not mix block types inside a single installation, which the specification does not permit.
Our Toronto shop makes the steel that a catalogue does not cover, fabricated steel bases, base plates, brackets, sleeves, spacer tubes, and structure connection hardware, hot dip galvanized after fabrication.
New runs, damaged rail replacement after a hit, height adjustment on existing rail, terminal replacement, and salvage and reinstatement of rail elements and blocks where the contract allows.
Custom metalwork made in Canada gives contractors, property teams, and facilities tighter quality control, faster lead times, and fewer cross-border delays. The work is fabricated in our Toronto shop, with Canadian steel and other metals selected when the application requires them.
We support your steel beam guide rail with Canadian-made fabrication, Canadian steel, clear local coordination, and a shop team close enough to solve site details before they become delays.
Steel beam guide rail, called SBGR on most Ontario tenders and W-beam guardrail in the field, is the run of corrugated steel rail bolted to steel or wood posts that redirects a vehicle away from a hazard. The Grate Guys supplies, fabricates and installs MTO-approved guide rail systems to the OPSD standard drawings and OPSS specifications named in your contract documents, including OPSD 912.101 and OPSD 912.532. That covers rail elements, channel components, steel and wood posts, offset blocks, fabricated steel bases, backup plates, spacer tubes, structure connections, transitions to rigid obstacles, and NCHRP 350 and MASH tested flared terminal sections.

Steel beam guide rail is a semi-rigid roadside barrier. A corrugated W-shaped steel rail element is bolted through offset blocks to a line of posts set at a fixed spacing. On impact the rail and posts deflect together, absorbing energy and redirecting the vehicle back toward the roadway instead of letting it reach whatever is behind the rail, a slope, a watercourse, a structure pier, a pole line, or a drop.
It is not the same product as the industrial guardrail that protects racking and equipment inside a building. Roadway guide rail is defined by published standard drawings and construction specifications, it has a specified mounting height range, a specified splice direction, a specified post and block combination, and an end treatment at each end that is engineered to handle a head-on hit.
If your drawings call up an OPSD 912 series detail, you need this page. If you are protecting a dock edge or a pick aisle from a forklift, our industrial guardrail systems page is the right one.
Ontario roadway guide rail is governed by a published set of drawings and specifications rather than by any one manufacturer's catalogue. The documents that normally control our scope are:
The edition and the specific drawing numbers named in your contract documents govern. Send us the guide rail sheets and the tender item list and we will confirm the system, the drawings, and the quantities before anything is ordered.
The post and block combination is a specification decision, not a preference. Steel posts are supplied to ASTM A36 and hot dip galvanized after fabrication to CSA G164, and they take either plastic blocks or routed wooden blocks. Where wooden breakaway posts are specified, they are installed with wooden blocks. Different types of plastic and wooden block are not permitted together within one steel beam guide rail installation, so we confirm the block type across the full run before the first post goes in.
Posts are set plumb and to the alignment and grade on the drawings regardless of what the auger finds. Acceptable material from the posthole excavation is used as backfill and compacted to OPSS 501. Tops of wooden posts are cut as specified and treated with two coats of copper naphthenate wood preservative, and any field applied preservative that touches a galvanized component is removed immediately so it does not attack the coating.
Where the drawings call for a fabricated steel base rather than a driven or augered post, for example over a structure, a retaining wall, or a slab, the base is installed level and square to the centreline of the roadway. Those bases, plates, and anchor details are steel we can make ourselves.
All joints are lapped in the direction of traffic so an impacting vehicle rides across the splice rather than catching the leading edge of a panel.
Post bolts are tightened to the specified torque, and on wooden post installations the bolts are field cut so no more than 10 mm protrudes beyond the nut, with the cut end ground smooth and every burr and sharp edge removed. Cut ends, field drilled holes, and any damaged galvanizing are repaired to ASTM A780. Flame cutting is not permitted on guide rail components.
Reflectors follow the specification rather than eye judgement, starting at the fifth post from the approach end of an end treatment, at a maximum of every tenth post on tangent, at closer intervals on curves per OTM Book 11, on the last post of the run, and on the posts at the four adjacent splices at the approach and leaving ends of a structure. One-sided reflectors on divided highways, two-sided on undivided.
Mounting height is measured vertically from the top of the steel beam guide rail, and the tolerance band is narrow enough that it has to be planned around final grade rather than corrected afterward. Steel beam guide rail without channel is normally finished within 685 to 735 mm, and rail with channel within 735 to 785 mm, with wider bands permitted during construction and seasonal shutdown. Type M systems and other proprietary systems sit in their own specified ranges.
Where curb and gutter is present, the point of measurement changes. When the face of the rail sits more than 300 mm beyond the back of the concrete curb, height is measured vertically at the face of the rail.
When it sits 300 mm or less from the back of the curb, height is measured at the edge of pavement. Getting that wrong is one of the most common reasons a guide rail item gets rejected at inspection, so we confirm the measurement condition against the cross sections before the run is set.
The end of a guide rail run is the part that has to be engineered rather than fabricated. We supply and install NCHRP 350 and MASH tested terminal sections, flared and tangent, energy absorbing and gating, matched to the approach speed, offset, and runout the drawings call for. Flared terminal sections are the common approach-end treatment on Ontario roadside runs, and leaving ends take the treatment specified on the guide rail sheets.
Terminals are installed strictly to the tested system's requirements, which is what the Ontario specification demands: where a proprietary system's requirements conflict with the general installation requirements, the proprietary requirements govern. Practically, we confirm which terminal the drawings call up, check the runout, flare offset, and grading the terminal needs behind and in front of it, flag it early when site conditions cannot deliver that, and submit the system selection and the applicable standard drawings to the Contract Administrator ahead of the first placement.
If your drawings still reference an older NCHRP 350 terminal and the road authority now wants a MASH tested unit, we will tell you before the order goes in rather than after.

A guide rail run that ends at a bridge parapet, a retaining wall, a concrete barrier, or a pier needs a stiffened transition so the vehicle is not pocketed where the flexible rail meets a rigid face.
Those transitions use nested or channel-backed rail, tighter post spacing, backup plates, and steel spacer tubes, and the offset block at the channel can be wood or a pipe sleeve over the connecting bolt, typically 89 mm outer diameter galvanized pipe cut to length. Sleeves and spacer tubes for transitions to concrete structures are fabricated from Schedule 40 galvanized steel pipe and galvanized after fabrication.
Connections into new or existing structure walls are made as specified in the contract documents. This is where a fabricator on the crew earns its keep: anchor plates, drilled and epoxied connections, packers, and shims for out-of-tolerance existing concrete are steel details we cut, weld, and galvanize in our own Toronto shop rather than waiting on a supplier.
Municipal roads, subdivision and site servicing work, and rural road shoulders where an OPSD detail is called up on the drawings.
Private roads, campus and institutional drives, and internal circulation roads that a road authority never inspects but that an owner still wants built to the public standard.
Industrial yards, truck courts, and loading areas where trailers, yard trucks, and heavy equipment need to be kept off tanks, transformers, racking lines, dust collectors, and building corners.
Parking facilities, including deck edges, ramp curves, and the transition from asphalt lot to structure, where guide rail is doing the work a low curb cannot.
Quarries, transfer stations, waste and aggregate sites, and any yard with steep edges, retaining walls, or ponds along a haul route.
Solar, substation, and utility sites where access roads run past equipment that cannot take a hit.
Most guide rail work in Ontario is not new construction. A run gets hit, a terminal is destroyed, a resurfacing job leaves the rail sitting low against new asphalt, or an inspection flags splices at every other post on an older installation.
On a damaged run we replace the deformed rail elements, post bolts, washers, and nuts, straighten or replace posts, reinstate the correct lap direction and torque, repair galvanizing to ASTM A780, and replace the terminal as a complete manufacturer's assembly rather than patching part of it.
On an adjustment, rail elements, channel elements, and wooden or plastic offset blocks are disassembled and salvaged for reinstallation where the contract allows it, existing steel offset blocks and front-face washers are removed and not reinstated, and everything goes back within the specified mounting height range using new rail elements where required and new post bolts, washers, and nuts.
Send photos and a location and we will tell you whether it is a panel swap, a full run, or a terminal, and what the road authority is likely to require before the lane reopens.
In Newmarket, steel beam guide rail usually comes down to site access, regional shipping, building use, exposure, measurement tolerance, and install timing. The Grate Guys treats each request as a practical scoping job: the quote starts with what must be measured, what load or use the part has to survive, and how the fabrication will reach the site.
The Newmarket checklist for this product covers the OPSD drawings called up on the guide rail sheets, system type and post spacing, steel or wood posts with the matching block type, mounting height against final grade and any curb, splice direction, transition and structure connection details, terminal selection with its runout and flare offset, and reflector spacing. That keeps the page tied to a real product and a real local project, with clear constraints, site details, and quote-ready information a buyer can act on.
Custom metalwork fabricated in Canada in our Toronto shop, then a tidy install, coordinated with concrete, drainage, doors, and surrounding work where site work is in scope.
Yes. The Grate Guys supplies and installs MTO-approved steel beam guide rail across Newmarket and the surrounding area, on roadway, municipal, private, industrial, and site servicing work. Turnaround is roughly 5-10 business days from quote to delivery.
Yes. We supply and install MTO-approved steel beam guide rail systems built to the OPSD standard drawings and OPSS specifications named in your contract documents, including OPSD 912.101 and OPSD 912.532. Send us the guide rail sheets for your Newmarket project and we confirm the system, the drawing numbers, and the quantities before anything is ordered.
Yes. We supply and install NCHRP 350 and MASH tested terminal sections, flared and tangent, energy absorbing and gating, installed to the tested system's requirements. Tell us which standard the Newmarket road authority accepts and we confirm the terminal on your drawings still qualifies.
Whichever ones your contract documents call up. In practice that is the OPSD 912 series, including OPSD 912.101 for the steel beam rail component and OPSD 912.532 for the installation detail, alongside the post, block, entrance, sideroad, transition, and end treatment drawings, with OPSS 1504 for rail panels and hardware, OPSS 1505 for channel components, OPSS 1503 for fabricated steel bases, and OPSS 1601 for wooden posts and blocks.
Both. Steel posts to ASTM A36, hot dip galvanized after fabrication to CSA G164, used with plastic or routed wooden blocks, or wooden breakaway posts with wooden blocks where the drawings specify them. We do not mix plastic and wooden block types within one installation, which the specification does not permit. Either is available for Newmarket work.
Across Newmarket, with work concentrated around Newmarket Business Park, Harry Walker Parkway industrial area, Leslie Street employment corridor, Davis Drive corridor, plus surrounding service areas so a multi-site project can stay with one team.
Mostly pharmaceutical manufacturing, advanced and precision manufacturing, automotive parts, healthcare, commercial retail. The Grate Guys works for road builders, general contractors, municipalities, developers, property managers, and industrial sites across Newmarket.
In Newmarket, the work has to account for precision-tolerance fabrication for automotive and pharma, hygienic stainless for life-science plants, healthcare facility platforms and screens, compact urban-industrial sites. On guide rail that means post embedment against local soils and frost, galvanizing that survives winter road salt, mounting height measured against final grade and any curb and gutter, and terminal runout that fits the shoulder actually available.
Yes. We replace damaged rail elements, posts, bolts, washers and nuts, reinstate the correct lap direction and mounting height, repair galvanizing to ASTM A780, and replace destroyed terminals as complete tested assemblies. Send photos and a location in Newmarket and we will tell you whether it is a panel swap, a full run, or a terminal.
Whatever the contract documents specify. Steel beam guide rail without channel is normally finished within 685 to 735 mm measured vertically from the top of the rail, and rail with channel within 735 to 785 mm, with proprietary systems in their own specified ranges. Where curb and gutter is present the point of measurement changes, so we confirm it against the cross sections before the run is set.
Yes. Resurfacing regularly leaves an existing run sitting low against new asphalt. We adjust the rail back into the specified mounting height range, salvaging rail elements, channel elements, and wooden or plastic offset blocks for reinstatement where the contract allows, using new post bolts, washers, and nuts. It is common work on Newmarket road contracts.
Yes. Where a run ends at a bridge parapet, retaining wall, concrete barrier, or pier, we install the stiffened transition the drawings call for, using nested or channel-backed rail, tighter post spacing, backup plates, and steel spacer tubes or galvanized pipe sleeves. Anchor plates, packers, and shims for out-of-tolerance existing concrete are fabricated in our own Toronto shop.
Yes, to the specification rather than by eye: starting at the fifth post from the approach end of an end treatment, at a maximum of every tenth post on tangent, at closer intervals on curves per OTM Book 11, on the last post of the run, and on the posts at the four adjacent splices at the approach and leaving ends of a structure.
From the tender items and the quantities on the guide rail sheets: length of run, system type, post and block type, transitions, structure connections, and the terminal at each end. The Grate Guys reviews the drawings for each Newmarket project and provides a clear, documented quote.
