With its incredible moisture resistance, it's a must if you're looking to create sturdy structures that can withstand increased humidity levels.
Block Board Grade and Types With Their Symbol
- BWP Grade (Boiling Water Proof) - Symbol: BWP
- MR Grade (Moisture Resistant) - Symbol: MR
- BWR Grade (Boiling Water Resistant) - Symbol: BWR
- Core Board or Particle Board - Symbol: PB
- Marine Plywood - Symbol: MP
These are the most common types of block board and their symbols.
It is important to select the right grade for each particular application, as this will affect the strength and durability of your project. Check with your block boards supplier when selecting a type of block board to ensure you're getting what you need!
The following is the step-by-step procedure for Block board Processing:
- The veneer layers are cut to the desired thickness and stacked together
- A thin layer of softwood is laid over the stack, forming a continuous sheet
- The edges of the sheets are trimmed to form a neat square or rectangular block
- Small wooden blocks are glued on both sides of the edges and then compressed tightly
- The blocks are left to dry and then sanded down to ensure a smooth surface finish
- The board is then sealed with adhesive glue and ready for use!
Properties Of Block Board
- Lightweight - Block Boards are lightweight and easy to handle, making them ideal for furniture pieces.
- Strength- The core of the block board is made up of wood strips, giving it great strength and stability.
- Moisture resistance - Boiling waterproof grade block board can withstand high moisture levels without warping or delaminating.
- Durability - The veneer layers on both sides of the block board protect it from wear and tear, making it a long-lasting product.
- Versatile - Block boards can be used for wall cladding, flooring, furniture pieces, partitions, and more!
Block Board Advantages and Disadvantages
- Compared to other engineered wood, it is undoubtedly the lightest in weight. The key benefit is that it is simple to transport and costs less to do so. They frequently appear in interior design because of their lightweight qualities.
- It is simple to handle and straightforward to deal with. The block board's processing requirements are low because the inside is built of solid wood strips, which makes it convenient for on-site building.
- Block boards have greater endurance and durability when compared to other engineering wood. They can display restraint even in a humid atmosphere with their moisture-resistant qualities.
- Compared to particleboard and MDF, block boards have strong and outstanding screw strength.
- The most eco-friendly engineered wood available is a block board. It costs less and gives you the real wood feeling while using very little glue.
- Block boards also have a flat surface, uniform hue, and a gorgeously grained wood veneer.
- Comparatively less expensive than plywood, essential for bringing down interior expenses.
- Although strong, it is not as robust and long-lasting as real plywood.
- Small gaps inside the core that form during production make it challenging to deal with the block board.
- This may impact the longevity of the furniture. Carpenters find it challenging to work because of the unavoidable space these gaps produce.
- The board may shrink or swell when exposed to specific conditions for an extended period.
- It is important to use caution when screwing and nailing because any gaps in the material's core could cause it to break.
- Some of the worst block board qualities include poor load-bearing and bending strength.
Block boards manufacturers Gujarat have a variety of advantages and drawbacks that make them suitable for specific applications. Block board is lightweight, cost-effective, moisture-resistant, and can be used in many different ways. However, it has poor load-bearing and bending strength due to the small gaps inside the core. It is essential to consider these pros and cons when selecting a block board for your project.
