What is the difference between the security door and the steel door?
Recommend you look at the national standard anti-theft door, April 1, 2008 promulgated a new standard.
Security door has a certain anti-destructive, steel door is the ordinary metal door! Work and materials are very different.
The essential difference is: anti-theft door countries have standard production standard, and steel doors do not need, just do not have qualified small workshops can be processed. Functional differences: anti-theft door with the basic anti-theft + insulation + noise + fire and other functions of the steel door customers decide their own, looking at the pleasing to the eye on it, huh, huh use difference: security door can be used as a household safety barrier steel door can be used Any place where there is no need for safety and security, except for the difference between the wet material: anti-theft door generally use cold-rolled steel plate filled with filler made of steel door you want to do what the line is smooth and open bargain Karma gang tied to burst it, As long as the material is steel :) Price difference: anti-theft door market price of 800-1500 ranging from the size of the steel door size calculation of material costs + artificial on the line do not know what else to think of these, I hope useful to you.
