What holds up an entire wall or floor slab while concrete is being poured? The answer might be a humble wooden beam — the H20 Beam.
The H20 Beam is a timber I-beam with a nominal height of 200 mm, serving as the core load-bearing component in modern formwork systems. Its top and bottom flanges are made of solid spruce or pine, while the web consists of multi-layer plywood, bonded together with weather-resistant adhesive into an "I" cross-section. Simple as it looks, the design is pure engineering genius: the I-shape delivers maximum bending stiffness with minimum material, weighing only around 5 kg per metre yet carrying loads far beyond its own weight.
Its applications are everywhere — slab formwork, wall formwork, column formwork, bridges, tunnels. Paired with steel props and film-faced plywood, it can be quickly assembled into a complete support system. The surface is treated with a water-repellent coating and both ends are fitted with protective plastic caps. With proper maintenance, it can be reused 200 to 500 times — a genuinely sustainable building material.
Compared with traditional solid timber, the H20 Beam offers more precise dimensions, more consistent structural performance, and far more reuses. Compared with steel beams, it is lighter, cheaper, and easier to cut on site. That is why, from residential buildings to skyscrapers and from domestic sites to overseas projects, the H20 Beam has become a near-universal standard in formwork construction.
A simple wooden beam, carrying the concrete skeleton of an entire building. Next time you pass a construction site, take a moment to notice these unsung, load-bearing heroes.
