Q:Aluminum alloy rolling doors and color steel shutter door that good
Aluminum Alloy shutter door instead of the traditional rolling door noise inherent shortcoming, the process of opening and closing of windleavesthe sound {(Note: the design of Aluminum Alloy shutter doors from the beginning not to seal, but the curtain sheet with a silencing strip sealinghas been improved, but still did not have the seal. ) the existing Aluminum Alloy shutter door curtain film have two Aluminum Alloy hollow extrusions and Aluminum Alloy filled polyurethane foam materials, extrusiontypecurtain, hardness, making width, protective performance are better than the filling profiles, in accordance with the free choice profile door curtain sheet to the different needs of users.
Q:What brand steel tapes are of good quality?
Personal feeling is also good for the Great Wall Seiko tape, upstairs several estimates are the production of steel tape manufacturers, of course, that their goods well. Our unit now buy all the Great Wall Seiko goods, said the tape is good, not because it is so durable
Q:Why can't the coil weight be too low?
Because the steel coil is stored in warehouse stacking level, if the coil weight is too low, resulting in a single coil capacity is reduced, so that the steel roll easily crushed and deformed;
Q:The difference between aluminized color steel roll and ordinary color steel roll
Ordinary color steel roll is a composite material, also known as color coated steel plate, is used in the continuous production line on the production line after surface degreasing, phosphating and other chemical coating treatment, painted with organic coatings, made by baking products. Both steel and organic materials are a little bit different. Both the mechanical strength of steel plate and easy molding performance, but also organic materials, good decoration, corrosion resistance.
Q:How can the outer diameter and weight of steel coil be converted?
When it comes to this question, in fact, a lot of them are irrelevant. The weight of the steel rolls means that there is a unit weight called the weight of each mm in the width of the steel coil
Q:Cold rolled steel coil steel, what is the difference?
Steel rolling process is different from the steel produced naturally different!
Q:Why can hot rolled coils be placed outside?
Because hot-rolled steel coils are generally used as raw material for semi-finished products, they have to be further used for pickling and cold rolling to make more use. The rust and dust can be removed after pickling
Q:Can cold rolled galvanized steel coils be acid washed after oxidation?
Hot rolling is made of slabs (mainly continuous billets) as raw materials. After heating, strips are made from roughing mills and finishing mills. From the last finishing mill stand out of the hot strip laminar cooling through to the set temperature, the coiling machine rolled strip steel roll cooled, according to the different needs of users with different finishing line (flat, straightening, transverse or longitudinal, inspection, weighing, packing and marking etc.) processing and become steel, flat steel product volume and slitting.
Q:A roll of 1 meters wide color steel roll about how many tons?
In general, between 3.5 and 5 tons. Our company uses 0.17*1000 white color steel roll. The weight is usually around 4.5 tons. Different manufacturers will have different sealing rolls.
Q:Is a steel plate the same as a steel coil?
Generally speaking, they can be used interchangeably, and the purchase price of the plate is slightly cheaper.
