C型鋼都是由C型鋼成型機(jī)自動(dòng)加工成型的。C型鋼成型機(jī)根據(jù)給定的C型鋼尺寸就可以自動(dòng)完成C型鋼的成型工藝。與傳統(tǒng)槽鋼相比，

相同強(qiáng)度可節(jié)省30%的材料。C型槽鋼作為支吊架的基礎(chǔ)受力構(gòu)件，可以和各種零部件 靈活配置，形成完整的結(jié)構(gòu)支撐體系；可以和墻體、地面、

天花板、混凝土、鋼結(jié)構(gòu)等各種結(jié) 構(gòu)構(gòu)件進(jìn)行連接； 新穎的軸向加筋設(shè)計(jì)增加了C型槽鋼的抗拉強(qiáng)度。C型槽鋼內(nèi)卷邊處有鋸齒，可以有效抗滑、

抗沖擊、抗 剪、方便整個(gè)系統(tǒng)可靠連接。

C-type steel is automatically processed by C-type steel forming machine.

The C-type steel forming machine can automatically complete the molding process of C-type steel according to the given size of C-type steel.

Compared with the conventional groove steel, the same strength can save 30% of the materials. As the foundation member of support hanger,

C-groove steel can be flexibly configured with various parts to form a complete structural support system;

it can be connected with various structural components such as wall, ground, ceiling, concrete and steel structure;

the novel axial reinforcement design increases the tensile strength of C-groove steel. There are serrations at the inner coil edge of the C-shaped groove steel,

which can effectively resist skid, impact and shear, and facilitate the reliable connection of the whole system.
