Advantage, particular use and scope of the grill board
BEST BET Brand grille board has the advantage as below compared with pattern steel and other grilles.
1、Save material: save the material most bearing the same load and reduce the material of supporting
structure accordingly.
2、Reducing investment: save material, manpower, time limit for a project , avoiding cleaning and
 maintenance.
3、Construction simple and convenient: firm with screw on the installation supporting, one person
   can finish it.
4、Save the time limit for a project : the production needn’t machining again in locale and install
very rapidly.
5、Durable: hot to soak zinc and antiseptic treatment before carrying out of the factory, bear the
  lash and stress.
6、Modern style: appearance attractive , design suitable ,ventilating , translucent and make
   human beings easy and smooth feelings.
7、Structure light and convenient : use material little , structure light and easy to install.
8、Avoid to accumulating dust : no accumulating rain ,ice , snow and dust.
9、Reduce the wind resistance : the wind resistance small and reducing the wind damage when windy because of good ventilating..
10、Design simple and convenient : dispense with the drawing of grille board ,only mark specification. The company can design for customers.
11、The capability of ventilating , light through a window , sending out the heat , flameproof and
slip resistance well.
