How To Choose The Right Plywood for Construction Projects?

High-quality construction plywood not only ensures project quality and construction safety but also effectively reduces project costs at the same cost level.

So, what constitutes good construction plywood? Next, Sunmmax will provide a detailed explanation of the key factors of high-quality construction plywood.

Glue:

Sunmmax uses strong waterproof phenolic resin glue, and the core veneer uses melamine glue. We have strict standards for the glue content of each veneer, controlling the glue content of small panels between 0.43-0.48 kgs and large panels between 0.8-0.9 kgs. The quality control department conducts random checks every hour. The glue viscosity must reach 180 or higher.

Core Veneer:

High-quality plywood selects high-quality raw materials. Sunmmax uses first-grade core veneer to ensure tight bonding and no voids inside the plywood, which is the basic guarantee for the service life of the plywood.

Pressure:

The core veneer must be treated with high temperature and high pressure to cure the glue, thereby producing sufficient bonding force and strength to ensure tight bonding between each layer of the core veneer.

Veneer:

Using whole sheets of face veneer with few or no knots is the basic condition for a flat and smooth board surface; secondly, using a certain concentration of phenolic resin glue, after hot pressing, the phenolic glue forms a waterproof and smooth film on the board surface, achieving excellent demolding effect.

Moisture Content:

The moisture content of construction plywood significantly affects its quality. The moisture content of construction plywood in the use environment is generally controlled between 8%-13%. If the moisture content of the plywood is too high, it will easily deform and crack during use, thereby reducing its service life and turnover times.

When purchasing construction plywood for international construction projects, one should not only focus on price but also consider multiple dimensions comprehensively to select plywood that meets project needs and is cost-effective. This will not only ensure project quality and construction safety but also save costs to a certain extent.
