Q:Want to buy anti-theft door, I do not know galvanized steel and cold-rolled steel plate where the difference? The same thickness which is good? The
Anti-theft door with galvanized steel and cold-rolled steel plate difference (in other conditions the same circumstances): cold-rolled steel plate high strength, good rigidity of the surface quality is also high, but the need to paint and other methods of ingot skeletons The rafters are resistant to atmospheric corrosion. Galvanized steel plate characteristics just the opposite. If you live in the south of the city, the environment is damp and rainy, it is best to choose anti-corrosion ability galvanized steel security door. Otherwise choose cold-rolled steel plate security door, because the price of cold-rolled steel security door should be slightly lower.
Q:What is the security standard?
The latest standard "anti-theft security door common technical conditions", the anti-theft door security level is divided into: A, B, C, D four levels. Anti-theft level classification level surface material thickness lock points anti-damage open time letters that a class 2mm12 ≥ ≥ 30minJ B class 2mm10 ≥ 15minY C class 1.8mm8 ≥ 10minB Ding 1.5mm6 ≥ 6minD general home security door to C, Ding-based, the higher the level, the higher the anti-theft performance. In addition to the door itself, the door lock is the key to anti-theft, the state will be anti-theft door lock cylinder is divided into three levels: level anti-technical open time anti-destructive opening time interoperability rate standard level A ≥1min≥15min≤0.03% National Standard B Grade ≥5min≥30min≤0.01% National Standard Super B Grade ≥260min≥30min≤0.0004% Enterprise Standard
Q:Downstairs security door alone pick up a lock line, how then ah?
Of course you can, and very simple. Only two of them can be used, it is recommended for each 4 core and a group, 8 core is divided into two groups, this can reduce the resistance. We find the electromagnetic switch, the first assumption that the electromagnetic switch is connected to the power supply negative, the other end is often connected with the drive tube. (If the contrary, the following program can be flexible to change their own) we only need one end of the first line of the network drive tube, the other end of the cable power supply is. Upstairs cable at both ends of a button switch can be.

Fence diameter of 14mm or more, the connection point a little more, not easy to be destroyed. In addition, no solder defects, door frames and door gap uniformity, opening and closing flexible, joint seal, etc .; plating solid, smooth, no defects.
