Assistance with formwork orders, hardware and site questions

Whether you are matching clamps to a panel edge, checking prop heights against a pour drawing, or working out which page covers quotes and delivery, this is where to start. The notes below point you to the right section of the catalogue and the right person to speak to before your crew is on site.

Questions crews ask before they order

Most of what comes through the inbox is about panel counts, clamp compatibility and how fast stock moves out of Johannesburg. Below are the answers we give most often. If your situation sits outside these, the contact page is the shortest route to a real reply.

How do I work out how many 600x1200 panels a wall needs?
Take the wall length and height, divide by the 600 mm and 1200 mm module, then add the corner and return pieces. Because the face is repeatable, the count you land on is the count you reorder for the next pour. Send the drawing dimensions with your quote request and we will check the panel count against the clamp and tie rod quantities.
Do the column clamps fit panels I already own?
The clamp jaws are cut to the folded edge profile used on our standard panels, and they cover a 200 mm to 800 mm column range with slotted side rails. If your existing panels use a different edge fold, measure the jaw opening and the fold depth before ordering, or bring a sample edge to the Johannesburg yard.
Which finish should I pick for a coastal site?
Galvanised is the default where salt air and wet stripping cycles are part of the week. Powder coating is worth it when the yard wants colour-coded stock for different wall sets or when panels sit outside between pours. Both finishes take the same clamps and tie rods, so the choice does not change your hardware list.
How is delivery handled outside Gauteng?
Stock is held in Johannesburg and moves to KwaZulu-Natal and the Western Cape on scheduled loads. Panel weight is stamped on each unit, so you can plan the offload and crane lift before the truck arrives. Tell us the site access and the offload method when you request the quote, and we will flag anything that affects the load plan.
When should a prop or clamp come out of service?
Each item carries reusability notes covering thread wear, jaw distortion and tube damage. Threads that no longer run cleanly by hand, bent outer tubes or jaws that will not close square are the usual retirement points. Replacement clamps and tie rods can be ordered on their own without rebuilding a full set.
Can I start small and scale up later?
Yes. A starter kit covers a first wall or column run, and the same module carries through to a full wall set, so nothing you buy early becomes dead stock. Bundles are quoted per project, which keeps panel counts repeatable when the next phase starts.

Still sorting out where to go next? The help page walks through ordering, quotes and delivery, and contact reaches the team directly.

Getting hold of the right person

Panel counts, clamp compatibility and stripping times are the questions that come up most often on site. Route them to the yard in Johannesburg and you get an answer from someone who handles the same hardware daily, not a call centre script.

If your question is already covered in the written notes, the FAQ and help pages usually save a phone call.

Phone the yard

Best for stock checks, delivery windows into Gauteng, KwaZulu-Natal and the Western Cape, and confirming whether a clamp set matches an existing panel edge.

Weekday response, usually same working day.

Email with drawings

Send pour layouts, column sizes or a panel schedule. Attachments help more than a description when you need a bundle quoted per project.

Collection and dispatch

Stock is held in Johannesburg. Give the panel weight and count when you book transport so the load is planned before the truck arrives.

Before you write in

Most repeat questions are already answered: load ratings, reusability notes, striking tools and cone systems sit in the written guidance.

Most of the calls we take are not about a single panel. They are about whether a clamp set will fit a 400 mm column, how many props a suspended slab cycle needs, or what a foreman should check on a galvanised panel that has been in a coastal yard for two seasons. Leave your details and we will come back with the specific answer, not a brochure.

If your question is about an existing order, a replacement clamp or a stripping sequence on site, say so in the message. That routes it to the right person faster.

Stay in touch

One short note when stock lands, when a clamp or tie rod spec changes, or when a delivery window to Gauteng, KwaZulu-Natal or the Western Cape shifts. No daily mail.

We use your details only to answer the question and to send the stock notes you asked for.
