Serrated U‑Beam Formwork Roll Forming Machine – Custom Roll Forming Machine Manufacturer

Tooth‑Pattern U‑Channel Concrete Formwork Beam Production Line

This roll forming system produces serrated (toothed) U‑beams used as load‑bearing horizontal members in concrete slab formwork systems. The teeth along the top flange provide positive grip for wooden planks or steel decking, preventing slipping. The machine forms 2‑3.5mm galvanized steel coil into U‑profiles with precision‑rolled tooth patterns. Inline punching creates end connector holes and tie rod slots. Speeds up to 6 m/min, cut‑off tolerance ±1mm. Ideal for formwork manufacturers supplying high‑load slab formwork for bridges, high‑rises, and industrial floors.

Description

Serrated U‑Beam Formwork Roll machining Equipment

– High‑Grip Support Beams for Concrete Slabs

The serrated U‑beam formwork roll former is a specialized line for manufacturing U‑shaped steel beams with serrated (toothed) top flanges. These beams are used as primary or secondary supports in concrete slab formwork systems. The teeth bite into wooden planks or steel decking, eliminating the need for additional fasteners and reducing assembly time.

Why serrated U‑beams?

Traditional smooth U‑beams require screws or clamps to hold decking, which is labor‑intensive and can damage the formwork. The serrated pattern provides a mechanical lock, allowing quick placement and removal of planks. The teeth are roll‑formed, not cut, preserving material strength.

Production process:

Uncoiling – Heavy‑duty uncoiler (10‑15 tons), coil width 300‑500mm.
Straightening – Leveling rolls.
Tooth rolling – Special roller dies emboss the serrated pattern (teeth) onto the top flange. Tooth pitch and height are customizable.
Servo punching – Creates end connector holes, tie rod slots, and lifting eye holes.
Roll forming – 10‑12 passes form the U‑shape. Rollers Cr12MoV, HRC58‑62.
Cut‑off – Flying shear cuts to length (±1mm).
Stacking – Powered stacker.

Key features:

Integrated serrations – Teeth are roll‑formed, not cut, ensuring consistent depth and strength.
High load capacity – Supports up to 30 kN/m span.
Corrosion resistant – Galvanized steel option.
Quick assembly – Planks snap into place without tools.
Heavy‑duty construction – Handles material up to 3.5mm.
