C型钢是经热卷板冷弯加工，由C型钢成型机自动加工而成的。C型钢成型机根据给定的C型钢尺寸就可以自动完成C型钢的成型工艺。
C型钢壁薄自重轻，截面性能优良，强度高，与传统槽钢相比，同等强度可节约材料30%。镀锌C型钢广泛应用于钢结构建筑的檩条，
墙梁，也可自行组合成轻量型屋架、托架等建筑构件。此外，还可用于机械轻工制造中的柱、梁和臂等。
镀锌c型钢是指在c型钢的表面镀锌，钢铁在空气中、水或者土壤中很容易生锈，甚至完全破坏。
每年因腐蚀而造成的c型钢损失约占产量的十分之一，而镀锌c型钢可以适用在各种强酸、碱、雾气等强腐蚀环境中。
镀锌檩条就是镀锌的檩条锌易溶于酸，也能溶于碱，故称它为两性金属。锌的标准电极电位比钢铁负。若基体是钢铁，
镀层破损或遭腐蚀生成Fe-Zn原电池时，锌镀层属于阳极性镀层，锌牺牲溶解，保护了钢铁。
因此钢铁上的镀锌层不是单纯的机械保护作用，而是通过电化学作用保护基体免遭腐蚀，即使锌层不完整也会起到这个作用。
更何况锌层的耐蚀性很大程度上决定于镀层上钝化膜的耐蚀性，钝化了的锌镀层其耐蚀性一般大约可提高8～20倍。
沿屋顶长度分布的水平部件，位于主椽上，支撑次要屋椽。古民宅用来挑起椽子，做成屋顶的横木，是建筑的主要构件之一。
C steel is processed by hot coil plate cold bending and automatically processed by C steel forming machine.
The C-type steel molding machine can automatically complete the molding process of C-type steel according to the given C-type steel size.
The C-type steel wall is thin and light-weight, excellent section performance, high strength, compared with the traditional trough steel,
the same strength can save 30% of the material.Galvanized C-type steel is widely used in steel structure building purlin, wall beam,
can also be combined into lightweight roof frame, brackets and other building components.In addition, it can also be used in columns,
beams and arms in mechanical light industry manufacturing.Galvanized c-type steel is galvanized on the surface of c-type steel,
which can easily rust or even destroy completely in air, water or soil.
The annual loss of c-type steel caused by corrosion accounts for about one-tenth of the output,
and galvanized c-type steel can be applied in a variety of strong acid, alkali, fog and other strong corrosion environment.
Galvanized purlin is galvanized purlin zinc easily soluble in acid, can also be soluble in alkali, so it is called an amphotropic metal.
The standard electrode potential of zinc is negative than that of steel.
If the substrate is steel and the coating is damaged or corroded to generate the Fe-Zn original battery, the zinc coating is an anodic coating,
which is sacrificed and dissolved to protect the steel.Therefore, the galvanized layer on steel is not a simple mechanical protection,
but through electrochemical action to protect the matrix from corrosion, even if the zinc layer is incomplete.What's more,
the corrosion resistance of zinc layer is largely determined by the corrosion resistance of passivation film on the coating layer.
The corrosion resistance of passivation of zinc coating can generally be improved by about 8~20 times.
Horizontal parts distributed along the length of the roof, located on the main rafters, support the secondary roof rafters.
Ancient houses used to lift the rafters, make the roof of the horizontal wood, is one of the main components of the building.
