H20 beam sizes

H20 beam is a critical component in construction formwork, defined by precise dimensions that balance strength and usability. Its cross-section follows a double T-shape, with consistent key measurements across manufacturers.

The standard cross-sectional height is 200 mm (±2 mm tolerance), while the width is 80 mm (±0.6 mm) . The beam comprises flanges and a web: flanges measure 80 mm (width) × 40 mm (height) , and the web thickness ranges 27–28 mm . This structure, certified to EN 13377 , delivers high load-bearing capacity despite weighing only 4.8–5.0 kg/m .

Length specifications offer flexibility for diverse projects. Standard lengths start at 1.8–1.95 m and extend to 5.9 m , with common options including 2.9 m, 3.3 m, 3.9 m, and 4.9 m . Customization allows lengths up to 6 m or even 8 m for specialized needs . These lengths integrate seamlessly with wall, slab, and column formwork systems .

Surface treatments like yellow waterproof paint and plastic end caps complement the dimensions, enhancing durability without altering the core size. This dimensional consistency makes H20 beams a universal choice in global construction.
