Wood formwork   is consist of panels and a support system. Panels are the part to shape the concrete, the support system is the part of the structure that stabilizes the panel's position and bears the upper loads. The quality of the formwork is related to the quality of the concrete project. The key points are in the accurate size, firm assembly, tight joints, and convenient assembly and disassembly. We should choose wood formwork according to the characteristics of the structure. 1. The basic formwork is made of pine board, poplar board, eucalyptus board, and the thickness of the ground beam side board is 20mm.  2. The bottom formwork of the main beam is made of pine boards, the thickness of the bottom formwork is 40mm, and the column formwork and floor formwork are made of machine-made wooden formwork with 12mm thickness. 3. The support system is made of fir logs, the diameter of the small head is not less than 70mm, and pulling connection take 400×500mm small square wood, and th

Plywood   is made by hot pressing of three or few layers of solid wood veneer or thin plate glued with a thickness of about one millimeter. When choosing plywood you should pay attention to the following points: ①Plywood has the difference between the front and the back. When selecting, the plywood should have a clear wood grain, a smooth and smooth front, and should be smooth touching and non-stagnant. ② The plywood should not have defects such as damage, bumps, hard wounds, and scars. ③The whole board has no degumming phenomenon. ④Some plywood is made by pasting two veneers with different textures together, so in the selection, it should be noted that the joints of the plywood should be tight and there should be no unevenness. ⑤ When choosing plywood, you should pay attention to selecting plywood that does not loose glue. If the sound is brittle when knocking on each part of the plywood, it proves that the quality is good, and if the sound is dull, it means that the plywood has been

When we wholesale  building formwork , we should know the construction sequence of building formwork, which are cushion formwork, foundation beam formwork, structural column formwork, column formwork, wall panel formwork, ring beam formwork, beam formwork, floor formwork and stair formwork.   The foundation of the cushion formwork in the building formwork is generally not high in height, but the volume is relatively large, so before installation, the centerline of the foundation and the elevation of the foundation should be checked. The structural column formwork can be divided into two types: the external wall structural column and the internal wall structural column; for the column formwork, before installation, the two sides should be the same as the long side of the column section according to the pop-up cross line and four peripheral lines. Plate, plus two plates with the short side dimension of the column section, assembled into a combined stereotyped formwork.   We can also unde

1.   MDF   is hard to both flex or crack. Although MDF is technically made out of wood, its structure is absolutely different. If you try to bend a MDF board it would rather snatch then warp. This is why engineered wood has the advantage of being resilient to moisture unlike its opponent. Of course, if you sink it in water, sooner or later the board will succumb to damage. But if you expose it to airborne moisture, the piece will expand and shrink as a whole while keeping the overall integrity and shape intact. 2. MDF is more affordable and easier to supply. Generally, MDF boards come at a lower price than natural wood. Of course, there are a few exceptions if you compared high-end MDF with some of the less pricey types of timber. Another great benefit of engineered wood is the fact that you can find it easier than i.e. maple or white oak, especially if you’re in need of a particular size. 3. MDF is easier to paint and seal. Contrary to solid timber, engineered wood lacks any specific

Plywood   grades come in four types, represented by the letters A, B, C, and D. Grades are a reflection of the superficial or cosmetic qualities of the wood. Plywood rating refers to the quality and appearance of veneers, whereas plywood rating is meant to inform you about the structural integrity and use cases. A-grade plywood is the best quality plywood. It will have a smooth, sanded surface with a visible grain but without knots. Any defects are filled in with synthetic filler, meaning the veneer can be easily painted without much preparation work. A-grade plywood is for use cases that emphasize the look of the wood over its functional properties, meaning it is excellent for furniture. B-grade is similar to A-grade plywood but will have defects. These defects must be minor and should measure no longer than 1-inch across.  C-grade and D-grade are unsanded and have several minor defects and knots. These will require some repair work, with C-grade featuring knots up to 1 1/2-inches acr
