DRAIN COVER SLABS

Reinforced concrete drain cover slabs, single and double reinforced, with matching galvanised mild steel angle frames. Cast at our own beds in Petaling Jaya.

Also on this page: GMS Angle Frames

The highest-volume line we cast. Slabs are supplied to the standard sizes below with Y12 bar top and bottom; the GMS angle frame is bought with the slab, not separately, and is sized from the slab it carries.

1. PICK THE SIZE

Four of our seven standard sizes. The rest are in the table below, and we also cast to your dimensions.

2. SINGLE OR DOUBLE REINFORCED?

Double reinforce takes the 65x65x6mm frame; single takes 65x65x5mm.

Concrete grade and load class are specified against your project and confirmed on the quotation, so we do not publish a single figure here.
