GRC composite column, which is better?
This is the performance of the GRC minimum guarantee project, not buried steel or cold wire drawing with pre inside, a few years will rust off, because the GRC thin wall, the protective layer is not enough, you should understand the serious consequences, you should also want to get it, the embedded metal should not be called GRC, GRC glass fiber reinforced cement component referred to, the use of metal is a short-term enhancement.
However, there is a point to remember to mechanical injection molding process, which, if alkali glass fiber, and its alkali resistant glass fiber weight of about 5%, the general 4.8%--5.5% (this can be calculated by their own checks).
Outsiders do not know, professional manufacturers say their good, or goods than three.
