CEMENT & MASONRY

Precast and civil items

Duty rating is the thing most often bought wrong, and the failure is sudden.

What this category covers

Lintels & beams

Precast RCC lintels in standard lengths and sections, for door and window openings in blockwork and brickwork.

Manhole covers & frames

RCC and cast iron covers in light, medium and heavy duty, with frames. Duty rating matters — a footpath cover under a vehicle fails once.

Gratings & drain covers

Channel gratings, gully gratings and trench covers in RCC, cast iron and steel.

Culvert & drainage pipes

RCC hume pipes and collars in standard diameters for culverts, storm drains and site drainage.

Stone, rubble & boulders

Rubble for foundations and soling, boulders for retaining and gabion work, laterite where specified.

Ready-mix concrete

Arranged from batching plants by grade and volume, with pour timing coordinated. Not held — scheduled against your pour.

Duty rating on covers and gratings

This is the item most often bought wrong, and the failure is sudden.

Where it goes	Needs	What happens otherwise
Footpath, garden, no vehicle access	Light duty	Fine
Driveway, car parking	Medium duty	A light cover cracks under a car within months
Access road, delivery vehicles	Heavy duty	Failure under a loaded truck, usually without warning
Industrial yard, forklift traffic	Heavy duty, steel	RCC covers spall under point loading from small wheels

Tell us what drives over it. A society that specifies a footpath cover for a gate entrance discovers the difference the first time a delivery lorry uses it — and by then the frame is damaged too.

What to send when ordering

Lintels

Clear opening width, wall thickness, bearing available each side, and whether it carries a slab above.

Covers & gratings

Clear opening size, frame or no frame, duty rating, and what traffic crosses it.

Culvert pipes

Internal diameter, class, total length, and whether collars are needed.

Rubble & boulders

Size range, quantity in cubic metres or tonnes, and site access for the tipper.

Ready-mix

Grade, volume, pour date and time, pump or direct discharge, and site access.

Every order

Delivery location, unloading arrangement, and whether the site can take the vehicle size involved.

Access decides the vehicle, and the vehicle decides the price. Precast and bulk items arrive on large vehicles. A narrow lane or a low cable changes the delivery, and it is cheaper to know before the load is made up.
