GI & GL Steel Price: Factors Affecting
A. Zinc thickness
Price depends on different thickness of zinc. For example, the price of 20 grams of zinc and 50 grams of zinc vary greatly. If the customer does not have requirements for zinc, it is recommended to select steel coil of about 30 grams of zinc. But the GL hould also indicate the aluminum content, and the price has big difference of GL with 25% and 55% aluminum content . If the customer uses the general environment, it can choose about 25% aluminum content. ; if used in wet, outdoor and perennial tropical climates, please choose GL with higher aluzinc content.
B. Coil basic steel thickness
The thinner the coil thickness, the higher the price. For example, the price of 0.13-0.16 is relatively high, the price change of 0.3-0.45 is small, and the price of 0.45-0.7 is basically the same. Because the thinner the area of the galvanized roll under 1 ton.It will be used more paint zinc longer processing time.
C. Packing
Packaging has simple packaging, standard export packaging and special packaging. Simple packaging, suitable for short-distance transportation, the outer layer is waterproof kraft paper protection, the protection performance is simple, and the price is cheap. The outer surface of the standard export packaging is waterproof kraft paper and galvanized iron packaging. The besides of the coil are also protected by galvanized iron. It is used for long-distance transportation and steel wire reinforcement in containers. It can better protect the color coated roll from the surface of the roll. And the waterproof effect is better. This type of packing is most widely used. Special packaging includes vertical packaging or customer requirements package. This packaging method can be used to calculate the price based on the packaging cost. The vertical packaging is such that the steel coil is the eye to the sky and fixed by a wooden pallet at the bottom of the coil. This packaging method protects the volume from external forces to the greatest extent, but the packaging cost and labor cost are high.
