The formwork plywood for sale
The plywood used for formwork is a kind of temporary supporting structure, which is made according to the design requirements, so that the concrete structure and components are formed according to the specified position and geometric size, maintain their correct position, and bear the weight of the building template and the external load acting on it. The purpose of the formwork project is to ensure the quality and safety of the concrete project, speed up the construction progress and reduce the cost of the project.

Types of plywood for formwork
Classified by material
According to the different materials used, the formwork is divided into wooden formwork, steel-wood formwork, steel formwork, steel bamboo formwork, plywood used for formwork, plastic plywood used for formwork, FRP template, aluminum alloy plywood used for formwork, etc.
Classified by structure type
Various cast-in-place reinforced concrete structural members have different shapes, sizes, and structures, and the structure and assembly methods of the formwork are also different, forming their own characteristics. According to the type of structure, the formwork is divided into: foundation formwork, column formwork, beam formwork, floor formwork, staircase formwork, wall formwork, shell formwork, chimney formwork, etc.
Classified by construction method
On-site assembling and disassembling formwork: On-site assembling and disassembling formwork uses fixed formwork and tool support; fixed formwork: all kinds of tire molds (soil tire mold, brick tire mold, concrete tire mold) are fixed formwork; mobile formwork: Such as chimneys, water towers, wall pillars used in concrete pouring of sliding formwork, lifting formwork and tube shell used for concrete pouring of horizontally movable formwork, etc.
Plywood for formwork material
Bamboo board
It is a building material that uses bamboo material as the main structure and filling material, and is formed into a blank by high pressure. It is suitable for horizontal formwork, shear wall, bridge and viaduct in housing construction. The surface of the bamboo board is smooth and flat, the construction effect is good, the water resistance is good, and it is not easy to be damp.
Poplar board
A multi-layer board-like material made of poplar wood rotary cut into veneer or wood square sliced into thin wood, and then glued with adhesive. Usually an odd number of layers of veneers are used and the fiber directions of adjacent poplar veneers are glued perpendicular to each other. The poplar board is light in weight, clear in texture, and low in cost.
Pine board
pine board is a commonly used building material in southern construction projects and is mostly used for house construction. The cost of pine board is high, but the turnover frequency is high, and it is not easy to expand and deform.
Eucalyptus board
Rotary cut eucalyptus into veneer or sliced into thin wood according to the wood square and glued together. Large-scale infrastructure such as houses, bridges, tunnels, nuclear power projects, as well as concrete art scenery, steel and aluminum frame template utilization, etc. The expansion coefficient is small, moisture resistance, high temperature resistance, and the construction surface is smooth and beautiful.
