H20 beam

The H20 beam is a core load-bearing component of the construction formwork system. It primarily consists of a laminated wood structure with an I-shaped cross-section, featuring high standardization, light self-weight, and strong load-bearing capacity. It is widely used for horizontal/vertical formwork support in cast-in-place concrete, and can be reused multiple times, resulting in low overall costs. The following provides a detailed introduction from all dimensions:

Material composition

Flange：New Zealand radiata pine

Web panel：3-layer/multi-layer plywood

Adhesive：Waterproof phenolic adhesive

Protection：Spray yellow waterproof paint on the surface/End with red plastic/iron protective head

Specifications

Beam height: 200mm

Flange width: 80mm

Flange thickness: 40mm

Web thickness: 27mm/30mm

Length: 2.45m/2.9m/3.3m/3.6m/3.9m/4.9m, etc.

Unit weight: 4.6-5.2kg/m. — 8m long, weighing approximately 41.6kg

Features

Lightweight and High Strength: It is approximately 60% lighter than metal beams with the same load-bearing capacity. It is 8 meters long and can be manually transported. It has strong load-bearing capacity, and the support spacing can be expanded, reducing the number of supports.

Stable and durable: LVL flange + multi-layer web + weather-resistant sealant, ensuring good straightness, no peeling, no cracking, and capable of being reused over 50 times under standard conditions.

Efficient construction: Standardized connectors are compatible with various templates, allowing for quick installation and removal, on-site cutting and assembly, significantly enhancing construction speed.

Environmentally friendly economy: Wood is renewable, surface treatment is environmentally friendly, high turnover reduces amortization costs, and the overall cost is lower than that of metal beams.

Strong adaptability: It can be used in horizontal, vertical, curved, and irregular formwork systems, adapting to multiple scenarios such as bridges, subways, and housing construction.

Highlighting Advantages

Cost advantage: The unit price is lower than that of steel components, with a turnover rate of over 50 times, low long-term amortization costs, and easy residual value recovery.

Efficiency advantages: Light weight, standardized connections, installation efficiency 30%+ higher than traditional supports, reducing labor and construction time.

Safety advantages: Stable elastic modulus, controllable deformation (l/500), weather-resistant sealant and protective treatment to reduce the risk of brittle fracture and corrosion.

Adaptation advantages: It can be customized according to span length, adapts to irregular working conditions such as curved molds, and has better versatility than fixed cross-section metal beams.

Applicable Scenarios

Horizontal formwork: For the main/secondary joists of floor and beam formwork, the support spacing can be adjusted to 1.2-1.8m based on the load.

Vertical formwork: The vertical joists of wall formwork, column formwork, and cantilever formwork enhance the flatness of pouring.

Special-shaped formwork: variable curvature formwork systems such as curved beams and curved walls.

Others: wooden secondary beams, load-bearing components of temporary stands/trestles, and formwork supports for subway/tunnel lining.
