1, aluminum alloy keel is not painted keel, painted keel is made of iron, aluminum alloy is made of aluminum alloy.
2, the aluminum alloy main dragon called the big T, the deputy dragon called the small T, the reason is different from the 50/30 main dragon used in the concealed part of the ceiling. And the deputy dragon, Zhonglong. Behavioral title.
3, aluminum alloy models, specifications are divided into many kinds: First, from the surface to distinguish, there are planes and grooves, two, from the color to distinguish between white lines, black lines and other colors! Third, from the matching board to distinguish There are 610, and 600 differences. (595*595 silicon calcium plate, the matching is 600*600 aluminum alloy keel specification, 603*603 silicon calcium plate, the matching is 610*610 aluminum alloy keel specification), four, according to their own differences, Also divided into large T, small T, corners.
4, the square ratio of aluminum alloy keel, (ie: how many large T, how many small T, how many corners), according to the general standard ratio is: large T0.54 / square meter, small T2 .7 / square meter, corner 0.134 / square meter. If the area is larger, the loss is smaller. Conversely, the smaller the area, the larger the loss.
