Shandong color steel coil manufacturers: how to choose the color steel coil color?

Shandong color steel coil manufacturers said, color steel plate color choice is mainly according to the match with the surrounding environment and the owner's hobbies, but from the point of view of the application technology, the light color coating pigment choice range is wider, you can choose excellent durability of inorganic pigment (such as titanium dioxide), and the coating heat reflection ability is strong (reflection coefficient is 2 times of the dark coating), the temperature of the coating itself in the summer is relatively low, is conducive to prolonging the coating Life.

Shandong color steel coil manufacturers remind everyone, even if the coating discoloration or chalking, light color coating and the original color of the contrast is also small, the appearance of the impact is not big, dark color (especially bright color) is mostly organic color, easy to fade in case of ultraviolet rays, three months discoloration, for the color coated steel plate, the coating and the steel plate of the coefficient of thermal expansion is usually different, especially the metal matrix and the organic coating of the coefficient of linear expansion of the difference is very large, when the ambient temperature changes, the interface between the substrate and the coating will produce expansion or contraction stress, if not properly released, the coating will crack.

Misconceptions in the domestic market: one is that there is a large amount of white primer in China, and the purpose of using white primer is to reduce the thickness of the topcoat, because the anticorrosive primer used in normal construction is yellowish-green (and therefore strontium chromate pigment), and it must have enough thickness of the topcoat, and secondly, the color-coated steel plates used in construction projects are color-coated steel plates of different manufacturers and batches from the same project and appear to be the same color in construction But different manufacturers of different coatings after several years of sun exposure, the color change trend is not the same, resulting in a serious color difference, there are too many such examples, even if the same supplier's products, for the same project is also strongly recommended to order a one-time, because different batches may use different paint supplier's products, which increases the possibility of color difference.

Color coated coil industry many people think that color coated coil packaging are the same, in fact, wrong, there are two kinds of packaging: horizontal packaging and vertical packaging, what is the difference between the two?

1. Horizontal packaging

Shandong color steel coil manufacturers said, horizontal packaging is horizontal color coated plate default factory packaging, iron wrapped, lined with moisture-proof paper, volume inner diameter 508/610mm; There are some special customer requirements, such as adding iron set, prevent coil collapse, plus iron set to additional charges, different manufacturers price is slightly different.

2.Vertical packaging

Shandong color steel coil manufacturers said, compared with the horizontal packaging, vertical packaging appeared later, its advantages are: transportation is more convenient, more solid, no need for iron sets, can avoid the coil collapse, so as to ensure that the color coated coil can be safe, without injury to the hands of customers.

Of course there is an additional cost, because when loading and unloading vehicles vertical packaging is more troublesome than horizontal packaging. With the improvement of customers' requirements on product quality, more and more customers choose vertical distribution.
