Waterproof Yellow H20 Wood I-Beam Construction Support (For Concrete Formwork)

H20 timber beam is a high-strength engineered wood beam certified to European standard EN 13377, named for its 200mm section height. It is widely used in concrete formwork support, floor slab/wall/bridge load-bearing systems, and serves as the core load-bearing component for heavy-duty formwork engineering.

Core Specifications (Standard Dimensions)

Section height: 200mm

Flange (top & bottom): 80mm (width) × 40mm (thickness)

Web (middle): 27mm / 30mm thickness (3-ply plywood / LVL)

Length: 1.8m – 6m (common sizes: 2.4m, 3.0m, 3.6m, 4.2m, 5.9m)

Weight: approx. 4.8–5.6kg/m, lightweight and easy to handle

Material & Structure

Flange: Nordic spruce/pine LVL (grade C24, moisture content ≤14%), knot-free and uniform in strength

Web: Finnish birch plywood, hot-pressed with waterproof phenolic adhesive, no delamination after 72-hour boiling

Connection: finger-joint technology + structural waterproof adhesive, excellent overall stability, bending and shear resistance

Surface: yellow waterproof and weather-resistant coating (UV-resistant, acid and alkali resistant); both ends equipped with red PP/metal end caps for impact and moisture resistance

Key Advantages

High strength & lightweight: Strength close to steel beams, only 1/5 the weight of steel; easy manual handling, reducing crane costs

Reusable & durable: Premium workmanship + end protection, recyclable 50–100 times, lower long-term cost

Stable & deformation-resistant: LVL flange + glued web, low shrinkage and swelling, straightness, no bending under load

Safe & reliable: EN 13377 / CE certified; bending capacity ≥5.0kNm, shear resistance ≥11.0kN, suitable for high-load projects

Strong compatibility: Perfectly matches 3-ply yellow formwork, WPC grid, and steel support systems

Efficient construction: Lightweight, easy to cut and splice, greatly improving formwork erection and stripping efficiency

Full Application Scenarios

1. Building Construction

Floor slab formwork support: Primary and secondary joists for floor slabs of commercial buildings, offices, and resettlement housing; stable load-bearing and high flatness with formwork

Wall formwork: Waling for shear walls, retaining walls, and basement walls; replaces square timber, less deformation, easier reinforcement

Column formwork: Peripheral support for square and circular columns, excellent shaping effect

Roof structure formwork: Load-bearing joists for cast-in-place concrete of sloped and flat roofs

2. Infrastructure & Municipal Engineering

Bridge engineering: Formwork support system for bridge box girders, bent caps, and abutments; suitable for long-span load-bearing

Subway & tunnel: Formwork support and temporary load-bearing frames for tunnel secondary lining and subway stations

Pipe gallery & culvert: Formwork joists for cast-in-place concrete of comprehensive pipe galleries, box culverts, and culverts

3. High-support Formwork

Main load-bearing beam for high-support systems of factories, stadiums, and shopping malls; high load capacity, high safety factor, ideal for high-altitude long-span formwork

4. Industrial & Special Buildings

Large-area floor and floor formwork for factories, warehouses, and logistics parks

Repeated use in standard floors of public buildings such as schools and hospitals

Cast-in-place concrete structure formwork for villas and low-rise residences

5. Temporary Works & Scaffolding Matching

Load-bearing beams for temporary construction platforms and operating platforms

Universal matching with steel supports, scaffolding, and aluminum formwork systems

Temporary load-bearing joists and partition frames on construction sites
