First of all, customers should understand that there are several grades of hollow sheets according to their quality, which can be generally divided into three grades: high, medium and average.
In order to meet the needs of different customer groups and customers, SZNL divided the products into three grades according to the warranty, 10-year warranty, 5-year warranty, and 3-year warranty.
As the saying goes, you get what you pay for.
In the face of too low a price, customers need to pay more attention when buying and selling to determine whether the product meets the required quality specifications.
At the same time, we should also pay attention to some merchants to the second best, if the money spent on a 10-year warranty to buy a 5-year or 3-year or even lower warranty products, that is not good.

Myth 1: Use your hand to squeeze the hollow sheet, thinking that the hard one is good.
In fact, this can only show that the specific gravity of the hollow sheet is sufficient, and the strength is naturally good.
But in fact, the transmittance is more important.
Hollow sheet surface is flat, whether there are bubbles, particles.
If the particles are larger and bubbles are more, it means that the raw material of sunshine sheet is poor and it is general sheet.
If the particles are smaller and the bubbles are less, it may be a better raw material.

Myth 2: The thicker the stronger.
The service life of hollow sheets is only related to the raw material and processing of sheets.

Myth 3: Accessories with cheap on the line, nails directly installed.
Good aluminum alloy accessories can make the leak-proof effect better.
A good adhesive strip can make the whole structure safe and soundless. (The place where the nails touch the board should be reamed by 20%)
