Product Description:

Galvanized Steel Coil gets coated in layers of zinc because rust won't attack this protective metal. The most external layer is all zinc, but successive layers are a mixture of zinc and iron, with an interior of pure steel. These multiple layers are responsible for the amazing property of the metal to withstand corrosion-inducing circumstances. Zinc also protects the steel by acting as a "sacrificial layer." If rust does take hold on the surface of Galvanized Steel Coil, the zinc will get corroded first. This allows the zinc that is spread over the breach or scratch to prevent rust from reaching the steel. For countless outdoor, marine, or industrial applications, Galvanized Steel Coil is an essential fabrication component.

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:Why can't the coil weight be too low?
And may make the level stacked steel coil collapse, rolling, produce production safety accidents.
Q:What are the characteristics of hot-rolled steel coils and cold rolled steel coils? What loading and unloading tools should be used? What items should be paid attention to?
When placing materials to roll on both sides of the main pad wood pallets, prevent rolling back and forth. In addition the floor should be thickened, cannot have uneven or debris, because the line of steel coils when gravity concentrated in contact with the ground floor, there is a fracture easily, debris, easy to leave the indentation in the steel roll.
Q:Steel coil from vertical to horizontal, what sling needs?
The sling has little effect, but it is easy to damage the surface of rolled steel.
Q:Several reading methods of steel tape measure
Direct reading method when measuring the steel tape zero scale alignment measurement starting point, proper tension (stretching force with steel tape tension or tension on the calibration ruler identification shall prevail, with the spring balance measure), direct reading measurement end point corresponding to the scale scale.
Q:The strip tower height
Causes: the strip has a larger snake shape; the take-up device holds the tension; the setting is unreasonable; the strip goes into the coiler; the centering is not good; the coil tension is not set properly.
Q:What is the maximum width of galvanized steel strip, please? The galvanized coat is 275, and how long is one coil?
But this kind of steel coil is not well processed in the market. At the beginning of Wuhan, several processing plants are good at processing, and other processing plants usually process 1850 at most.
Q:What's the difference between hot rolled coil and hot-rolled carbon thin steel coil?
The difference between hot rolled primary and hot-rolled carbon thin steel coils is that they include carbon steel rolls and low alloy steel coils.
Q:How to solve steel plate storage
The warehouse temperature should be constant, prevent the occurrence of condensation, a horizontal steel coil to pile up, forced to pile up, in contact with each other at the coil not binding belt lock, steel roll room felt material, narrow roll on wide roll, roll on roll light. In order to facilitate the lifting, the steel coil and the wall should be kept a certain distance.
Q:On how to reinforce steel coils in a container
In the bottom and sides with a thick strip stuck, but also to ensure that the wood will not loosen down...... Rough steel rolls, I saw people loading and unloading on the docks, poked them directly with a small forklift truck, and then reinforced with wooden planks
