Heavy duty expansion joint covers for high-load areas

When the joint sits under trucks, buses, forklifts or constant trolley traffic, standard architectural covers wear out fast. The Genotek heavy-duty range - 18 systems for joint gaps from 10 mm to 500 mm - uses thicker aluminium sections, reinforced nosings and high-frequency fixing patterns to take repeated dynamic loads without loosening or plate rattle.

Movement coverage includes thermal, seismic and settlement, so these systems suit loading docks, service corridors, bus stations, fire-truck access routes and podium slabs carrying maintenance vehicles. Recessed heavy-duty pans keep surfaces flush where materials-handling equipment needs a smooth path; surface-mounted plate systems allow retrofit over existing joints with minimal downtime. Load capacity depends on gap width, support conditions and wheel type - send us the actual vehicle and wheel data for your route and we will size the system to the duty.
