Q:Aluminum alloy rolling doors and color steel shutter door that good
Hello, the shutter door material mainly galvanized steel plate, color steel plate, aluminum alloy, stainless steel, PVC soft board, PVC soft door curtain.
Q:Steel coil from vertical to horizontal, what sling needs?
Consider using the function with hydraulic prop hanging clamp from the coil center will hold tight after hanging up, then put in a L type hydraulic turnover device platform or unilateral double column loading platform, then L platform can realize 90 degrees down, vertical horizontal variable.
Q:How to solve steel plate storage
Avoid steel plates touching the ground, fixing steel coils, and using pads to reduce accidental or dangerous movement.
Q:What is the accuracy of steel tape inspection
In addition, the project is through the detection of steel tape, steel tape each batch have the error him different, so do projects each into a batch of steel tape has to go through the inspection department, let this batch of steel tape has reached the same error range. All the measuring tools in this project are unified into these steel tape measures, so that the measurement error is guaranteed
Q:Where are the coils and the steel plates used? Where did the steel plate come from?
The use of steel coils, refrigerators, washing machines, household appliances, and other industries, parcels are winding.Steel plates can also be found everywhere: airplanes, guns, trains, ships, space shuttles, spaceships, automobiles, etc..Steel plate through mining - sintering - iron smelting - smelting - forming.
Q:What's the best material for color coated steel coil?
Color steel roll is a kind of composite material, also called color coating steel plate. It is produced by continuous coating on the production line by surface degreasing and phosphating etc. after being coated with organic coating, the product is made by baking. Color steel roll is a composite material, both steel and organic materials, both of them a little. Both the mechanical strength of steel plate and easy molding performance, but also organic materials, good decoration, corrosion resistance.
Q:A roll of 1 meters wide color steel roll about how many tons?
Color steel roll is a composite material, both steel and organic materials, both of them a little. Both the mechanical strength of steel plate and easy molding performance, but also organic materials, good decoration, corrosion resistance. 1 meters wide should also have length, wall thickness conditions to know how many tons. The manufacturer is generally in accordance with customer requirements into a volume, the normal width of 1 meters per roll over 1 tons.
Q:The strip tower height
Elimination measures: strictly control the shape of plate and reduce the serpentine; according to the different specifications of the strip, set up the take-up system; set the coiling tension of the strip.
Q:How are steel tape measures installed?
That's the tape measure. There's a small card with no card in the middle of the screw! So it can't be retracted automatically! The solution is to wrap the open tape to the end!
Q:What's the length of a coil of cold rolled steel? Is there a standard?
In 2.0*1000*C calculations, it is assumed that the formula for the length of 5T in this volume is 5000/ (2.0*1000*1000*7.93) = the total number of meters. First, the weight of one meter is calculated by dividing the total weight by the single weight, that is, the theoretical length of the volume
