Description
Eco-Friendly Formwork Beam | Lightweight, Reusable
Product Overview

The PVC Plastic I-Beam is a next-generation formwork reinforcement beam designed as a direct replacement for traditional timber walings, timber studs and wooden beams in cast-in-place concrete construction.
Extruded from high-strength engineering PVC, the I-beam combines a wide top/bottom flange with a thinner central web — an I-section profile that delivers excellent bending resistance while keeping self-weight to a minimum. It is purpose-built for wall formwork, column formwork, slab/shoring systems and beam sides, pairing directly with plastic formwork panels, plywood or steel formwork.
Where timber beams warp, rot, absorb water and are discarded after a few uses, the PVC I-Beam stays dimensionally stable, weatherproof and reusable across 50–80 construction cycles — with 100% of waste and off-cuts recyclable at end of life.

Key Features
- Ultra-lightweight – Easy to handle, carry and install by hand; reduces labor intensity and speeds up erection and stripping.
- High compressive & bending strength – The engineered I-section carries heavy concrete loads without flexing, splitting or snapping under pressure.
- Waterproof & moisture-proof – Does not absorb water, swell, warp or delaminate; unaffected by rain, wet concrete or humidity on site.
- Fire-resistant & anti-mold – Inherently flame-retardant and immune to rot, mildew, termites and insect damage — no treatment needed.
- 50–80 reuse cycles – Far outlasts timber (typically 3–6 uses), dramatically lowering the cost-per-formed-square-meter.
- No release agent required – Smooth, non-stick surface strips cleanly from concrete; no oiling, no secondary plastering, fair-faced finish.
- Fully recyclable – Off-cuts, damaged pieces and end-of-life beams are recycled and re-extruded, delivering a true low-carbon, zero-waste formwork solution.
- Fully customizable – Standard mold sizes below are in stock; other heights, flange widths and web thicknesses, plus any cut-to-length, are manufactured to order.
Available Sizes
Standard extrusion molds currently available. Dimensions refer to cross-section (see diagram: a = beam height, b = flange width, c = web thickness). Length can be produced to your project requirement.


Custom cross-sections and lengths are available on request — contact our engineering team for your formwork drawings.
Typical Applications
- Wall & column formwork (horizontal walings / strongbacks)
- Slab and ceiling formwork joists / support beams
- Beam sides and beam formwork
- Tie-back and soldier beam systems
- Compatible with plastic, plywood and steel formwork panels
