6.0M Doka H20 Timber Beam From Chinese Manufacture

I. Core Function (Template System)

The H16 and H20 timber beams serve as the primary structural keel for both horizontal and vertical formwork setups. When integrated with formwork plywood, steel frames, or aluminum frames, they create a highly reliable, load-bearing framework tailored for demanding construction environments. Their precise engineering ensures that scaffolding systems like ringlock, cuplock, or adjustable steel props interface flawlessly with tie rods, wing nuts, and clamps, creating a unified and secure pouring environment.

• 1) Horizontal formwork (floor / bottom of beams): Acting as the main load-bearing keel, the H20 beam directly supports the formwork panels and the massive weight of poured concrete. This optimized load distribution significantly reduces the required number of supporting uprights, clearing floor space and accelerating project timelines.
• 2) Vertical formwork (walls / columns): Positioned as the sturdy back keel for wall and column forms, the timber beam resists the intense lateral pressure generated by wet concrete. The rigidity of the beam ensures absolute accuracy during pouring, preventing bulging and maintaining strict dimensional tolerances.
• 3) Special formwork: Highly adaptable for complex architectural designs, these beams easily integrate into curved, irregular, and hydraulic climbing formwork setups, providing a dependable backbone for challenging geometries.
• 4) Bridge / infrastructure: Extensively utilized in heavy civil engineering, they provide critical formwork support for massive concrete structures, including bridge piers, box girders, and foundation blocks.

II. Why Use H16/ H20 beam (Core Advantage)

Selecting the right structural timber beam dictates the efficiency and safety of your entire concrete pouring operation. Our 6.0M Doka-compatible H20 beams are engineered to deliver exceptional performance, structural reliability, and long-term value across multiple dimensions.

• 1) High cost-effectiveness: The I-shaped section provides maximum mechanical efficiency while maintaining a surprisingly light weight of about 4.6kg/m. Workers can easily transport and position these beams manually, drastically reducing reliance on heavy lifting equipment and minimizing labor expenditures.
• 2) Stable and durable: We source premium European spruce for the flanges, known for its dense, straight grain. The moisture content is strictly controlled and kiln-dried to around 12%, ensuring the wood emits a natural, fresh timber scent while remaining highly resistant to warping or splitting. Combined with a multi-layered plywood or three-layer solid wood web, the beam maintains exceptional straightness. It resists water, acids, and alkalis, allowing for hundreds of reuse cycles.
• 3) High versatility: Fully compliant with EN 13377 standards, this beam integrates smoothly with global mainstream formwork systems (such as Doka, Peri, etc.). Whether splicing or extending, the precise dimensions guarantee a snug, secure fit every time.
• 4) Economical Life Cycle: The initial investment amortizes rapidly due to the beam's extended lifespan. For large-scale, repetitive concrete projects, the cost per pour drops significantly compared to conventional timber.
• 5) End Protection & Durability: To combat inevitable site impacts, we offer multiple end-protection solutions. Choose from chamfered ends coated in waterproof resin, impact-absorbing plastic caps, or heavy-duty steel end covers. These shield the vulnerable end grain from moisture ingress and physical crushing.
• 6) Export Certifications & Clearance Support: Navigating international procurement is straightforward. Our beams meet stringent EN 13377 criteria, and we actively assist in securing necessary phytosanitary and fumigation certificates, ensuring smooth customs clearance.
• 7) OEM Customization & Branding: As a direct manufacturing source, we provide custom logo printing and brand marking directly onto the distinctive yellow web, allowing distributors to build local brand recognition directly on the construction site.

Technical Specifications

Before deploying any structural component, verifying its physical and mechanical properties is essential. The table below outlines the exact specifications of our H16 and H20 timber beams. The flanges are crafted via a high-strength finger-jointing process, resulting in a visually smooth, continuous surface that feels solid to the touch and produces a sharp, resonant sound when tapped—a true indicator of dense, void-free wood. The web is bonded using premium melamine or phenolic adhesives, ensuring the layers remain tightly fused even after prolonged exposure to wet concrete and rain.

2) H20 beam with metal cover

The heavy-duty steel end caps provide maximum defense against crane impacts and rough handling, preserving the structural integrity of the beam ends during rapid site deployment.

3) H20 beam with plastic cover

Impact-resistant plastic end covers offer a lightweight yet highly effective barrier against moisture penetration and edge splintering, ensuring the web and flanges remain intact.

4) H16 beam with plastic cover

The slightly lower-profile H16 beam, also protected by durable plastic caps, is ideal for projects requiring lower load capacities but demanding identical reliability and precision.

5) Packing and loading 

Beams are securely strapped, bundled, and loaded with precision to ensure they arrive at your global destination in pristine, ready-to-use condition without transit damage.

FAQ

1) What are the appearance quality standards for H16/ H20 beam?

We maintain rigorous visual and structural standards. Running a hand along the flange reveals a flawlessly sanded, smooth finish, entirely free from decay, disruptive large knots, or hazardous cracks. The multi-layer web board is bonded under extreme pressure, ensuring absolutely no glue cracking, delamination, or swelling from moisture exposure. Visually, every single beam is perfectly straight, presenting a crisp, linear profile without any bending, bowing, or twisting, which is crucial for maintaining level concrete pours.

2) What are the advantages of H16/ H20 wooden beams compared to solid wood beams?

Traditional solid timber is unpredictable; it absorbs water rapidly, causing it to warp, crack, and snap under load, typically rendering it useless after just 5 to 15 pouring cycles. In stark contrast, the engineered I-profile of the H16 and H20 beams distributes stress efficiently. Protected by weather-resistant coatings and end caps, these beams can reliably endure 50 to 150 uses. When calculating the lifecycle expense across multiple projects, the amortization is remarkable: the per-use cost of an H20 beam is roughly 1/3 to 1/5 that of conventional solid wood, freeing up significant project capital.

3) How to choose H16/ H20 wooden beams, steel back ribs, and aluminum beams?

The choice depends entirely on your project's specific mechanical demands and budget. To achieve the optimal balance of cost-efficiency, impressive turnover rates, and reduced physical strain on workers, the lightweight H20 timber beam is the definitive choice for standard horizontal and vertical formwork. If your project involves exceptionally high walls or extreme concrete pressure that demands massive load-bearing capacity, heavy-duty steel back ribs are selected. Conversely, for specialized architectural high-end projects where weight reduction and ultimate precision are paramount, premium aluminum alloy beams are the preferred alternative.
