What Is the Difference Between Bamboo Plywood Sheets and Timber Formwork?

People often ask what the difference between bamboo plywood sheets and timber formworks is, which is more cost-effective and how to choose? In order to solve the doubts, the difference between bamboo plywood sheets and timber formworks will be distinguished as follows.


Plywood sheet is a collective term in construction formwork, which includes bamboo plywood sheets and timber formworks. Both are suitable for the construction of cast-in-place concrete frames, shear walls and tube structure templates in industrial and civil buildings. Although their uses are similar, their actual differences are quite big if you know more.


1. Material of bamboo plywood sheets and timber formworks


(1) Bamboo plywood sheet


The structure of all bamboo mats and thin bamboo curtains, without wood chips and other impurities, ensures the consistency of water absorption and expansion rate of the template and the unique bonding strength and toughness of bamboo plywood.


(2) Timber formwork


Pine full core board is used as the main material, which is no cavity in the middle of the board after sawing. The surface coating is phenolic resin with strong waterproof performance to ensure that each timber formwork can achieve superior performance.


2. Strength of bamboo plywood sheets and timber formworks


(1) Bamboo plywood sheets


It is made of bamboo curtains after throwing pieces of bamboo which are of short kinds and long kinds. When forming the sheet, it is composed of long and short pieces interweaved, and then combined by high temperature and high pressure to have higher strength.


(2) Timber formwork


After pine veneer and eucalyptus veneer have been glued, they are first cold pressed and then hot pressed for secondary molding.


3. Features of of bamboo plywood sheets and timber formworks


(1)Bamboo plywood sheet


The surface is flat and smooth while the adsorption force for concrete is only 1/12 of that of the timber formwork. It is easy to demould and has high strength, good toughness, no deformation and good resistance of acid and alkali and water. It will not come unglued in boiling water for 120 minutes or soaking in water at room temperature 96 hours. Thus, it has higher turnover times and longer service life.


(2)Timber formwork


It has light weight, strong strength and easy processing but less turnover than bamboo plywood sheets.


Generally speaking, the performance of bamboo plywood sheet is higher than that of timber formwork. Bamboo plywood sheet has a wide range of uses. In addition to construction projects, it is also especially suitable for railways, highways, rivers and seas bridges, such as cast-in-place beams, continuous beams, tunnels, viaducts, dams, subways, and various containers, automobile bottom plates, and brick plate. So, how to make a suitable choice between the two when purchasing? First of all, it depends on whether the project has higher quality requirements for the plate. If the turnover is more than 10 times, bamboo plywood sheet should be selected. Secondly, it is whether the price is acceptable. The performance of bamboo plywood sheet is much higher than that of timber formwork, so the price must be higher than that. The right choice should be according to your needs.
