1, look at the door, the door material, the door deformation, sag is actually a problem of the door.
The door cover on the market mainly has two kinds, density board and solid wood multilayer board. Density board is made of wheat orange, straw, sugar cane and other materials cut into powder and pressed. Although its balance is good, it is easy to crack and deform, and the wood has poor nail holding power.
And the solid wood multi-layer is made of multi-layer solid wood veneer criss-cross superposition, has a strong nail force to eat nail force, good stability, waterproof and moisture-proof, is the home wooden door.
2, look at the material, there are many kinds of material, environmental protection standards?
This depends on whether to provide you with a written guarantee, will be anything said without evidence, written into the contract.
Solid wood material cost performance is good; Environment-friendly metal door is too heavy, long time will fall, easy to damage; Paint door panels look good, but afraid of touch afraid of scratches; Blister door for a long time will bubble; The durable of fire prevention board fights coarseness pretty good.
3, look at the brand and the manufacturer's production equipment, a good brand has quality assurance, but also has good after-sales service. Whether the equipment is complete, good production equipment can make beautiful paint effect, can control the moisture content of the wood, reduce the probability of wood cracking, deformation, prolong the service life of the product.
