H20 Timber Beam: The Backbone of Efficient Concrete Formwork Systems

For contractors and formwork engineers, the support beam is critical to the safety, speed, and cost of any concrete pouring project. H20 timber beams have become the global standard for wall, slab, and column formwork — offering an ideal balance of strength, light weight, and durability for residential, commercial, and infrastructure construction.

What Is an H20 Timber Beam?

An H20 timber beam is a lightweight, high-strength engineered wood beam with an H-shaped cross-section. It consists of laminated veneer lumber (LVL) flanges and a multi-layer plywood or OSB web, bonded together with waterproof structural adhesive. The H20 design maximizes strength while minimizing weight, making it the preferred choice for concrete formwork support structures.

Why Contractors Choose H20 Timber Beams

1. High Load Capacity

Despite their light weight, H20 timber beams deliver exceptional structural performance. Depending on span and configuration, they can support up to 20–25 KN per meter of distributed load — sufficient for most wall, slab, and bridge formwork applications.

2. Lightweight & Easy Handling

A standard 3.9m H20 beam weighs only 18–22 kg. This allows for manual handling and fast assembly without heavy lifting equipment, reducing labor costs and improving on-site safety.

3. Excellent Durability & Reusability

Manufactured with waterproof phenolic resin adhesive, H20 beams resist moisture and delamination. With proper care, they can be reused 50–100 times, delivering excellent long-term value for contractors with multiple projects.

4. Perfect Compatibility

H20 beams are designed to work seamlessly with aluminum or steel formwork systems, as well as traditional timber shoring. Standardized dimensions ensure compatibility with most formwork accessories — clamps, brackets, props, and tie rods.

5. Versatile Applications

From high-rise slabs to bridge decks, H20 beams adapt to virtually any concrete forming scenario.
