Knowledge of angle steel

Commonly used in all kinds of building structure and engineering structure, such as the beam, Bridges, transmission tower, lifting transportation machinery, ships, industrial furnace, reaction tower, container frame and warehouse shelves of construction steel, Angle steel plays a very important role in the construction industry, is the vast number of builders and building materials dealer always focus on topic.

On both sides of the cross section is equal to the Angle called equilateral Angle steel, otherwise known as unequal Angle. Can according to the structure of the different needs of different kinds of mechanical components, also can make members between joints, is very important in engineering and metal frame connection, steel Angle for recognition, shaanxi inovance steel pipe has the following Suggestions:

First of all, demanding quality documents. Certificate of product quality is qualified written documents to prove its product production enterprise, has the legal effect. The certificate must be asked for when purchasing the steel quality.
