Modular steel formwork panels, clamps and casting accessories

Standard 600x1200 panels, adjustable column clamps, tie rods, slab props and cone systems, held in Johannesburg and delivered to Gauteng, KwaZulu-Natal and the Western Cape. Every item carries panel weight, load rating and compatible hardware so foremen can plan pours, stripping times and transport loads before the truck is loaded.

What the hardware looks like up close

Panel edges, clamp jaws and prop threads are where formwork sets either hold a line or start leaking. These three views show the parts crews handle most often on a pour cycle.

Oss-Form products — Panel edge profile

The folded edge on a 600x1200 panel is what the clamp jaws bite onto. Stacked like this in the yard, panels are counted and checked for edge damage before they go onto the truck.

What the Oss-Form catalogue actually covers

Panels, clamps, tie rods, props and the small parts that decide whether a pour goes smoothly. Every line item carries its own weight, load rating and hardware match, so a foreman can plan stripping times and truck loads before the order is placed.

Modular steel panels

Standard 600x1200 faces pressed from 3 mm steel, with folded edges that take clamp jaws without shimming. Galvanised for coastal yards, powder-coated where stock needs colour coding.

Column clamps and tie rods

Slotted side rails and threaded ties square columns from 200 mm to 800 mm. The same jaws fit wall returns, so crews carry one clamp set instead of a box per column size.

Slab props and cone systems

Props in three extended heights with the safe working load stamped on the outer tube. Drop heads and cone plugs share the tie rod thread, keeping the site hardware pool small.

Striking and release tools

Wedges, spanners and cone release keys sized to the clamp and prop range. Stripping sequence notes sit with each item so panels come off clean and edges stay straight for the next cycle.

Project-quoted bundles

Starter kits for small teams, full wall sets for civil contractors. Bundles are quoted per project so panel counts repeat across floors rather than being guessed on site.

Stock and delivery

Held in Johannesburg and dispatched to Gauteng, KwaZulu-Natal and the Western Cape. Replacement clamps and worn tie rods can be added to an existing bundle without rebuilding the order.

What leaves the Johannesburg yard

Three lines cover most of what civil crews, precast yards and small building teams ask for. Panel weights, load ratings and compatible hardware sit on every item, so a foreman can check a pour drawing against the catalogue before the truck is loaded.

Stacked steel formwork panels with folded edges in a yard

600x1200 Modular Steel Panel

Standard panel for wall and slab pours

This is the panel that most site teams order first, because it sets the module for everything else in the wall set. The 600x1200 face is pressed from 3 mm steel with a folded edge that takes standard clamp jaws without shimming. Galvanised finish is the default for coastal work, and powder-coated panels are available where the yard wants colour-coded stock. Each panel is weighed and stamped so foremen can plan transport loads and crane lifts before the truck leaves Johannesburg.

Steel column clamp hardware assembled around a concrete column form

Adjustable Column Clamp Set

Four-piece clamp for square and rectangular columns

Column work is where most small teams lose time, because every column size needs a different box. This clamp set uses slotted side rails and a threaded tie to pull the form square across a 200 mm to 800 mm range. The jaws are cut to match the folded edge of the standard panel, so the same clamp works on wall returns and isolated columns. Striking is done with a spanner and a wedge, and the set is supplied in a steel carry frame that doubles as a stacking pallet.

Slab props and drop head hardware supporting a suspended concrete slab

Slab Prop and Cone System

Props, drop heads and cone plugs for suspended slabs

Suspended slab work needs props that can be set, loaded and struck in a predictable order, and this package is built around that cycle. Props are supplied in three extended heights with the safe working load stamped on the outer tube, so the foreman can match them to the pour drawing without a separate table. Drop heads and cone plugs are sized to the same thread as the tie rods, which keeps the hardware pool small on site. Reusability notes on each item cover thread cleaning and the point at which a prop should be taken out of service.
