Plywood industry has been a major partner for the construction works. From external cladding to interior panels, from beds to countertops, there are numerous applications of plywood in home and office construction. Marine grade, commercial, fire-resistant and moisture-resistant are some of the top names that come to mind when we think about plywood. But shuttering plywood is the underrated variety, without which the construction industry cannot be imagined. Builders and residential building contractors choose reliable shuttering plywood manufacturers for quality assurance. By knowing the basics about this plywood, they make a well-informed selection of the manufacturer and the materials.
Why Construction Projects Need This Plywood
Concrete is the most utilized material in construction works. It forms the structural elements as well as decorative designs, whether they are buildings or single-storey homes. The composition of wet cement and crushed stones needs to be cured over a certain period of time before it hardens.
How Shuttering Plywood Ensure Curing of Concrete
As the columns and beams are elevated, the concrete poured into the reinforced structured needs a boundary within which the proper form of columns or beams can be made. This supporting boundary is shuttering plywood. The other names for this plywood are centring and formwork plywood.
Making of Densified Shuttering Plywood
● Hardwood veneers are boned by phenol formaldehyde resins under high temperature and pressure.
● The density of the core is higher than that of an average plywood.
● Glue with enough adhesion strength and waterproof properties ensures a BWP grade is obtained.
● A phenolic film is applied on the surface of the densified shuttering plywood for additional water resistance and surface smoothness that helps in demoulding.
● In some cases, the plywood is calibrated for dimensional evenness and stability.
Features To Expect
Here are the top features one should expect from the shuttering plywood manufacturers:
1. Waterproof Material
Wet concrete can be highly corrosive and instantly rot the plywood from the inside. Having a waterproof surface is necessary for the formwork.
2. Edge Protection
The edges are prone to water and moisture ingress. Therefore, tightly protected edges are an essential feature in the shuttering plywood.
3. Nail holding
The plywood needs to remain sturdy till the concrete hardens. It should not get weaker as the load due to the curing process increases gradually. Hence, the screw holding capacity should be sufficient.
How To Choose a Shuttering Plywood Manufacturer
Choosing the best among various shuttering plywood manufacturers is about making an assessment based on certain factors. These are:
● Check the specifications that the manufacturer follows while making this plywood. IS: 4990 is the defined Indian standard for shuttering plywood of high grade.
● Evaluate the build quality of the samples. It should be heavy when being lifted, and the surface should be smooth without bumps or voids.
● Knock across the surface and notice the sound. If there are variations, the plywood has an inconsistent core.
● Compare the prices for similar specifications. Prioritize overall value rather than MRP.
● Prefer film-faced plywood for medium to heavy construction works as these have higher repeatability.
Conclusion
Plywood industry is evolving, but a few of its functions and valuable uses will never change. The shuttering plywood has always been a reliable type for concrete construction works. With improved manufacturing technologies and innovations by the shuttering plywood manufacturers, the construction industry is getting advanced formwork solutions. The top companies like Northern Plywood are bringing an innovative range to the table. The density, core structure, finishing are all being enhanced with the research and development.
