01Overview
The HWC-CS series combines a modular steel build with ready-mix concrete filled on site, giving it the durability of a concrete deck with the faster install of a modular structure. Suited to corrosive or rusty environments where a pure steel deck wears faster.
02How it works
Steel skeleton, concrete fill
A composite weighbridge starts as a modular steel structure, similar in principle to a pure-steel modular deck, but instead of a bare steel plate serving as the running surface, the modules are designed with a form into which ready-mix concrete is poured on site and cured. The steel does the structural load-carrying work; the concrete provides the wearing surface a vehicle actually drives on.
Why concrete outlasts bare steel in the wrong environment
A bare steel deck plate, exposed continuously to abrasive traffic and a corrosive atmosphere — chemical fumes, salt air, acidic runoff from certain bulk materials — wears and corrodes faster than concrete does in the same conditions. Concrete doesn't rust, and a worn concrete surface can typically be resurfaced rather than requiring structural steel replacement.
Installed as pit-type or pitless
Because the underlying structure is still a modular steel frame, a composite deck can be configured either way — set into a pit for a flush installation, or mounted above grade — the concrete fill is a surface-and-durability choice layered onto whichever structural configuration suits the site.
03Manufacturing & build quality
The steel modules are fabricated the same way as a standard modular weighbridge — cut, jig-welded, blasted, and coated — but built with an internal form and reinforcement mesh designed to receive a concrete pour rather than to serve as the finished running surface on their own. The modules ship to site and bolt together in the usual way, and once the structural frame is assembled and load cells fitted, ready-mix concrete is poured into the formed modules on site and left to cure to design strength before the bridge is put into service. Because the concrete pour happens on site rather than in the factory, mix design, slump, and cure conditions are controlled to local site conditions, and the finished surface is checked for level before load cells are trimmed and the system is calibrated.
04Problems it solves
Corrosive or rust-prone environments
Sites handling fertiliser, chemicals, salt, or other corrosive bulk materials chew through unprotected steel decking far faster than concrete, which doesn't have a corrosion failure mode in the same way.
High-abrasion, high-wear traffic
Constant heavy-axle traffic wears any deck surface over time; a worn concrete surface can generally be resurfaced on site, where a worn steel plate typically means panel replacement.
Sites wanting steel's install speed with concrete's durability
A fully cast-in-place concrete weighbridge takes much longer to build than a modular one; a composite design gets the faster modular assembly while still finishing with a concrete wearing surface.
Long-service-life expectations
Where a site expects decades of continuous heavy use and wants to minimise the lifecycle maintenance burden of the deck surface itself, concrete's durability profile is generally the better long-run bet over bare steel.
05Why it matters
Choosing deck material isn't a cosmetic decision — it's a bet on how the weighbridge will hold up against whatever that specific site throws at it for the next couple of decades. A composite deck exists for the sites where a pure-steel deck's corrosion or wear profile would mean a shorter, more expensive service life: fertiliser plants, chemical yards, coastal sites, anywhere the atmosphere or the material being weighed is actively hostile to bare steel. Getting that material choice right up front avoids a mid-life deck replacement that a slightly different specification would have avoided entirely.

09Frequently asked
How long before the bridge can be used after the concrete pour?
Concrete needs to reach its design cure strength before carrying vehicle traffic — the exact timeline depends on the mix and site conditions, but it's a materially longer wait than a bolt-together pure-steel deck, and is factored into the installation schedule up front.
What capacity range is available?
Composite construction is offered across the same general capacity range as steel-only modular and welded designs — the concrete fill is a durability and surface choice, not a capacity constraint.
How is the concrete surface maintained over time?
A worn or spalled concrete surface can typically be repaired or resurfaced on site without disturbing the underlying steel structure or load cells, which is generally simpler than replacing a worn steel deck plate.
Can it be installed as pit-type or does it have to be above ground?
Either — the composite deck is a steel structural frame with a concrete fill, and that frame can be configured as a pit or pitless installation the same way a pure-steel modular deck can.
Is it more expensive than a standard steel weighbridge?
It generally costs more up front than a bare-steel deck of the same capacity, due to the additional site concrete work, but is typically justified by a longer service life in corrosive or high-wear environments where a steel deck would need earlier replacement.
