Many consumers purchase plywood based on the recommendations of carpenters, workers, contractors or suppliers. They rarely get to understand and analyze the quality aspect of the plywood. Often they compromise on quality for cheap products without realising the long term impact of purchasing sub standard materials.
Is it not surprising that consumers complain of deterioration of the plywood bought after just a few years. The common complaints heard are:
- Bending in the material
- Material has been infected with Fungus / Termites.
- Material has become powdered
- Material has developed cracks
So how did the above happen?
Plywood industry is very prone to
- Duplicate items
- Sub standard raw material used to manufacture plywood.
Be aware that many items that are sold under popular brands are duplicates. Fake Stickers or Stamps are put on the material to make it look genuine
Sub standard raw material used to manufacture plywood:
It is important to understand that the quality, strength and durability of Plywood is linked to:
- Wood used. Does the wood used have natural properties that are termites or fungus proof? So always ask which wood or set of wood is used to manufacture.
- Glue that is used to bind the layers in a sheet.
- Machinery used.
To short cut cost, quality is often compromised by some manufacturers. Plain jungle wood is used that do not withstand termites or fungus or water moisture.
Bad glue materials are used for binding layers in a sheet, thus resulting in cracks, bend, etc.
How to avoid duplicates or Sub standard materials ?
It is important to understand what grade of material is being purchased. Generally plywoods fall under Commercial (Moisture Resistant), BWR (Boiling water Resistant) and BWP (Boiling water proof) also known as Marine grades.
Indian Standard Specifications CODE for
1) Moisture Resistant(MR) Grade Plywood is IS:303 of 1989
2) Boiling Water Resistant(BWR) Grade Plywood is IS:303 of 1989
3) Boiling Water Proof(BWP) Grade Plywood is IS:710 of 2010
Look out for the ISI Mark on the material (plywood Sheet).
BIS Mark or CM/L Number:
Materials should have CM/L number which indicates the authenticity of the material using the ISI mark.
Consumers can download the BIS Care app from Google Playstore. They can track the history, manunfacturing unit of the material using the app and by providing the CM/L number mentioned on each sheet of plywood.
THe app can be downloaded from:
- Do not fall prey to unsolicited advice
- Always do your own research and study of the material
- Look for ISI mark on the material
- Look out for CM/L number on the mateial
- Understand the source and usage of raw materials used.
