Products Description
This high-strength LVL timber is made of multiple layers of high-density veneer under high pressure, resulting in a dense overall structure, high bending strength, and outstanding load-bearing capacity. It is a core material for concrete formwork, formwork joists, scaffolding accessories, beam and column supports, and temporary building frames on construction sites. Its load-bearing capacity far exceeds that of traditional solid timber. It is resistant to bending, breaking, and splitting even after repeated use, and can fully withstand the lateral pressure, vibration impact, and foot traffic during concrete pouring. It features uniform dimensions, excellent straightness, and high compatibility with steel formwork and bamboo plywood, effectively improving formwork accuracy and concrete forming results. It is widely used in various civil engineering projects such as high-rise residential buildings, commercial complexes, bridges and roads, factory infrastructure, municipal engineering, and prefabricated buildings. It is also suitable for temporary site fencing, protective frames, and material stacking dunnage. It is a primary material for long-term bulk purchases by general contractors, labor teams, formwork rental companies, and building material wholesalers.

Application scenarios of formwork at construction sites
Concrete Wall and Column Formwork Support Frame
Serving as the main internal support frame for wall, square column, and irregular column formwork, it tightly supports the formwork surface, offsets the lateral pressure generated by concrete pouring, and prevents formwork bulging, deformation, and grout leakage. The uniform strength of the timber frame ensures consistent stress across the entire row, guaranteeing the verticality and flatness of the walls and columns, resulting in standardized and aesthetically pleasing concrete components.
Cast-in-place Floor Slab and Beam Bottom Load-bearing Support
The main load-bearing frame beneath the bottom formwork of floor slabs and frame beams bears the long-term weight of wet concrete, as well as the loads from construction personnel and tools. Its high-strength structure is resistant to bending and sagging, effectively controlling the floor slab elevation and flatness, and preventing common construction problems such as floor slab settlement and cracking.
Site Scaffolding and Temporary Protective Structure Auxiliary Materials
Using steel pipes to construct temporary scaffolding, safety railings, and construction operation platforms, it provides auxiliary support. Combining toughness and strength, it resists impact and bending, improving the overall stability of temporary facilities and ensuring on-site construction safety.
Temporary wooden blocks for material stacking and equipment storage on construction sites
Used as bases for building materials and equipment such as steel bars, pipes, and small machinery. They evenly distribute heavy pressure, isolate ground moisture, prevent materials from getting damp and rusting, and prevent equipment from tilting. They are also resistant to repeated rolling and dragging, making them suitable for the rough working environment of construction sites.
High-strength Material and Core Performance Advantages
Thick, high-density veneer is made from carefully selected large-diameter logs, rotary-cut, eliminating defects such as knots, hollows, rot, and diagonal grain. A multi-layered, cross-grain assembly process is used, combined with high-strength construction-grade structural adhesive, and then molded in one piece under constant temperature and pressure using a large-tonnage press. The entire structure is free of voids and soft layers, resulting in comprehensive upgrades in four core properties: bending resistance, compression resistance, splitting resistance, and impact resistance, ensuring stable mechanical properties. Strict moisture content control prevents water absorption, deformation, mold, and decay during open-air storage and in alternating wet and dry environments on construction sites. Excellent straightness ensures no natural bending of the entire log, allowing for precise formwork positioning. Wear-resistant and impact-resistant, it is suitable for complex conditions such as handling, impacts, and trampling on construction sites, allowing for repeated reuse and offering outstanding overall cost-effectiveness.
High-Density Thick Veneer Substrate: Solid Foundation of Strength: High-quality log veneer with straight grain and dense fibers is selected. The veneer is of uniform thickness and high density, improving overall load-bearing and bending resistance from the raw material level, eliminating bending problems caused by insufficient local strength.
Interlaced laminated structure, dispersed stress and prevents fracture. The scientifically interlaced arrangement of the wood grain alters the direction of stress, effectively dispersing lateral pressure from concrete and concentrated impact loads. Lateral bending and longitudinal compressive strength are doubled, reducing the likelihood of whole-piece fracture or splitting under stress.
High-strength adhesive layer for strong bonding, preventing delamination. Using water-resistant and aging-resistant industrial structural adhesive, the adhesive layer boasts high bonding strength. It will not delaminate, separate, or bubble under conditions of sun exposure, rain, and temperature fluctuations on construction sites, ensuring structural integrity even after long-term reuse.
Precise moisture content control ensures dimensional stability in both dry and wet environments. Gradual drying locks in the equilibrium moisture content, resulting in low water absorption during open-air storage and rainy weather. It is less prone to swelling, shrinkage, and twisting, maintaining standard cross-sections and straightness, ensuring precise formwork dimensions.
Durable and fatigue-resistant, reducing construction material costs. The material has a balance of toughness and hardness, and will not break down quickly after repeated disassembly, handling, impact and trampling. The number of times it can be reused far exceeds that of ordinary solid wood, effectively reducing the labor and material expenses for frequent material replenishment and replacement on the construction site.
Production Process and Precision Craftsmanship for Building Formwork
The entire process revolves around high strength, high straightness, durability, and ease of construction. The complete workflow includes: mechanical screening of raw materials + manual re-inspection, segmented gradient drying, fully automated CNC gluing, multi-layer staggered assembly, constant temperature and ultra-high pressure hot pressing, long-term stress curing, precision cutting to size, precise sanding on all four sides, and neat end finishing. Intelligent management throughout the entire process ensures uniformity in size, strength, and straightness of timber within the same batch, with neat, burr-free edges and corners. On-site nailing, cutting, and splicing are convenient, fully meeting the standardized operational requirements of building construction sites.
Double Raw Material Screening to Strictly Control Defective Boards
First, mechanical scanning removes veneers with holes, cracks, and large knots. Then, manual re-inspection of each piece ensures that every substrate meets quality standards, preventing weak raw materials from entering the finished product.
01
Gradient constant temperature drying balances internal and external moisture
A multi-stage slow drying process is used to gradually adjust the moisture content of the veneer, avoiding the brittleness and cracking caused by high-temperature rapid drying. This also ensures consistent moisture content throughout the batch, adapting to varying construction site climates.
02
CNC uniform glue application ensures a full and even glue layer
Fully automated glue application equipment applies glue at a uniform speed, resulting in a uniform glue layer thickness, complete coverage, and balanced interlayer adhesion. This eliminates the risk of localized delamination and improves overall structural stability.
03
Ultra-high pressure constant temperature hot pressing ensures a dense and integrated internal structure
A large-tonnage press maintains constant pressure and temperature, tightly compressing the veneers without gaps or soft areas. The overall density is uniform, and the load-bearing capacity of each section of wood is completely consistent.
04
Long-term stress curing eliminates the risk of deformation
After hot pressing, the veneer is placed in a constant temperature workshop for static curing, fully releasing the internal stress generated during pressing and cutting. The finished product is straight and does not warp, preventing natural warping or deformation during later use.
