Before You Order
Confirm your product requirements and collection or delivery arrangements before ordering.
Yes. Request a combined materials and freight quote with your sleeper lengths, finishes and quantities, specified steel sections and drainage accessories. We confirm availability and delivery arrangements for your order.
Send the delivery suburb, postcode, product quantities, preferred date and site access and unloading details. Freight is assessed against the actual address, load and access requirements before ordering.
Typical delivery is 2–3 business days, subject to stock, transport scheduling, order size and site access. Confirm the timing for your address and order before scheduling installation.
Standard lengths are 1,800 mm, 2,000 mm and 2,400 mm, with 80 mm thickness, 40 MPa concrete and 2 × N12 reinforcement. Confirm the required span, finish and specification against your approved design.
Use your approved engineering or designer’s steel schedule. Final selection depends on loading, ground conditions, post spacing and connections; wall height alone is insufficient. Send the specified steel sections and post lengths with your quote request.
