Development trend of galvanized sheet metal:

- May 02, 2018 -

Development trend of galvanized sheet metal:

First, using high quality base board, on the surface of the substrate, strip shape and dimension accuracy requirement is becoming more and more high, outdoor use such as small zinc flowers smooth level off hot dip galvanized steel coil, zinc galvanized steel coil in a timely manner under the rise of zinc alloy hot dip roll;Indoor use such as galvanized steel coil, laminated cold rolled sheet and aluminum sheet.

Secondly, improve the pretreatment process and pretreatment fluid, the equipment quantity is small, the cost is low to become the mainstream technology, continuously improve the stability of the pretreatment fluid, the corrosion resistance, the environmental protection performance.

Third, pay attention to the development of new coatings, to general polyester, poly (vinylidene fluoride) (PVDF) and modified plastisol, super color reproducibility, uv resistance, resistance to sulfur dioxide, improve the corrosion resistance;Develop functional coatings such as pollution resistance and heat absorption.

Fourth, the unit equipment is more perfect.For example, new type of welding machine, new roller coating machine, perfect curing furnace, advanced automatic instrument and so on.

Fifth, because of the low cost of cold-pressed flowers, it has the characteristics of aesthetics, three-dimensional sense and high strength, making the production technology of cold-pressed flower become the trend of development.

Sixth, pay attention to product diversification, functionalization, high grade, such as deep impact type color coating board, "teak skin" color coating board, anti-static color coating board, anti-pollution color coating board, high heat absorption color coating board and so on.
