Product Texting

1. Impact test: 12.7mm diameter punch, 500g hammer, 50cm height impact, tape, 180-degree angle of fast peeling, paint film adherence is good, no shedding.

2. Bending test (T-bend): 180-degree angle bending molding, bending arc inner diameter of 3 times the value of the board thickness (3T) tape, 180-degree angle of the tape, fast peeling, good adhesion of the paint film, no shedding. (0T has special requirements)

3. Solvent resistance test (M.E.K) dipped in M.E,K or toluene gauze on the surface of the board to apply about 1 kg force to wipe back and forth 100 times the topcoat, 50 times the backcoat, did not see the substrate.

4. Salt spray test, accelerated weathering, chemical resistance (5% sulfuric acid, 5% sodium hydroxide)

Product Packing

Each coil to be securely tied with two bands through the eye coil and one circumferential, the contact points of these bands on the coil edge to be protect with edge protectors. Coil then to be properly wrapped with water proof/resistant paper, it then to be properly and completely metal wrapped. And each packed coil to be properly wrapped with band, three-six such band through the eye of coil at about equal distance, and two-four such bands securely tied around belly of coil at about equal distance.

The main production processes of the color coated coils includes pre-treatment process, coating process, and baking process.

•   Steel pipe: Black pipe, Galvanized steel pipe, Round pipe, Square pipe, Rectangular pipe, Spiral pipe, etc

•   Steel sheet/coil: Hot/Cold rolled steel sheet/ coil, Galvanized steel sheets/coil, PPGI, Checkered sheet, corrugated steel sheet, etc;

•   Steel beam: Angle beam, H beam, I beam, C lipped channel, U channel, Deformed bar, Round bar, Square bar, Cold drawn steel bar, etc

1. Galvanize plate literally means an alloy structure. Its main components are aluminum, which accounts for about 55%, and zinc which is 43.4%. In addition, 1.6% silicon is added, and it is formed after high temperature A kind of plate. Its corrosion resistance is very outstanding, and its durability is also very excellent.

2. It has heat reflectivity and good heat resistance. Compared with galvanized sheets, the price is slightly more expensive, but the service life is longer, so the price/performance ratio is also very high.

3. The thermal reaction performance of a galvanized sheet is very high, more than twice that of galvanized steel sheet, so it can be used as a heat insulation material. In addition, it can withstand high temperatures of more than 300 degrees and can be used in chimney pipes fluorescent lampshades, etc.

4. In addition, it is easy to paint and has relatively good adhesion. It can be painted without weathering treatment, so it can be painted directly on the board. In addition, the processing performance and spraying performance are very superior, and they can be used in construction, including automobiles, home appliances, etc.
