Concrete Cover Grating 100x5 With Flat Cross Bar
The heaviest published cover section: 100x5 bearing bar with a 30x5 flat cross bar, hot-dip galvanized, for wide openings and vehicle loads.
Product Overview
At 100 mm deep and 5 mm thick, this bearing bar is being asked to span, not just to carry. It is the section for a wide chamber or a trench that has to be crossed by vehicles without an intermediate support underneath, and the 30x5 flat cross bar is substantial enough to distribute load between bearing bars rather than simply hold them apart. These panels are heavy by design, so how they are divided and how they will be lifted is part of the drawing rather than an afterthought.
Key Benefits
- Spans a wide opening without an intermediate support in the chamber
- 30x5 flat cross bar distributes wheel load between bearing bars
- Divided and detailed for mechanical lifting from the outset
- Same galvanized finish and hook detail as the lighter covers in the range

What It Looks Like
Photographs of this product taken by the factory, lit and in production. Nothing here is a rendering of a product that does not exist yet.
Who It Is For
- Civil contractors on heavy industrial and port works
- Plant engineers covering wide service trenches
- Municipal works departments on road and yard drainage
- Fabricators supplying covers into infrastructure projects
Problems It Solves
- Wide openings that would otherwise need a support wall built in the chamber
- Covers that fail because the span, not the load, was underestimated
- Panels too heavy to handle safely because lifting was never designed in
- Mixed-source covers where frame and panel do not match
Application Scenarios
- Wide drainage and service trenches crossing vehicle routes
- Large inspection chambers in industrial yards
- Culvert and sump covers where no intermediate bearing is available
- Heavy plant areas where covers are crossed by loaded trucks
Technical Features
- Bearing bar 100 x 5 mm carbon steel
- Cross bar 30 x 5 mm flat
- Hooks, banding and lifting provision fabricated with the panel
- Hot-dip galvanized after fabrication
- Panel division set by span and lifting method together

Use Guide
- Confirm the clear span before the section: at this depth the span is usually what governs
- Plan the lift before delivery; these panels are not a hand-lift item
- Bed the frame fully so load transfers into the concrete, not into the frame alone
- Bolt down where vehicles brake, turn or reverse across the cover
- Re-check seating after the first weeks of traffic
Quality Control
- Bar section verified on incoming material as well as on the finished panel
- Panel flatness and squareness checked at this weight before banding
- Lifting point welds inspected
- Coating checked in the deep bar cavities, not only on the surface
Materials
- Carbon steel bearing bar and cross bar
- Zinc coating applied by hot-dip galvanizing
Manufacturing Process
- Drawing and 3D model
- Cutting and stamping
- Pressure welding or press locking
- Framing and fabrication
- Surface treatment
- Inspection and packing
Certification Standards
Production follows TBC, the source specification publishes no certification marks. Certificates are sent per product on request rather than posted publicly, because the documents a shipment needs depend on the destination market.
Customisation Options
- Span and division to your chamber layout
- Lifting eyes, sockets or purpose-made lifting keys
- Bolt-down and anti-theft fixings
- Frames, angle surrounds and end plates
How It Compares With The Alternatives
A technical comparison against other ways of solving the same problem. Nothing here is a performance claim against a named competitor product.
| Against a stock panel cut to fit on site | A stock panel trimmed on site loses its banding, its bar pitch at the edge and its coating at every cut. This one is drawn to the opening and coated after it is fabricated. |
| Against buying the panel and its frame separately | Panel, banding, hooks, frame and handrail are fabricated and coated in the same plant and the same batch, which is what makes them fit each other. |
