Q1: Why buy Materials & Equipment from

A1: All products offered are carefully selected from China's most reliable manufacturing enterprises. Through its ISO certifications, adheres to the highest standards and a commitment to supply chain safety and customer satisfaction.

Q2: How do we guarantee the quality of our products?

A2: We have established an advanced quality management system which conducts strict quality tests at every step, from raw materials to the final product. At the same time, we provide extensive follow-up service assurances as required.

Q3: What’s the Processes Flow of Flat Steel Bars?

A3:The steel flat bar is made through three processes:

1.Feeding the material: Feeding the row material (the steel plate) to Slitting Line.

2.Slitting:The steel plate would be slitted into expected width by lengthways cutter.

3. Leveled and cutting: The plat bar would be ground into level by the grinder and then cut into required length.

Q:Are galvanized flat steel and angle steel the same price?
No, generally speaking, galvanized flat steel is more expensive than angle iron
Q:Cold rolled flat steel standard. What is cold rolled flat steel?
Flat steel, width 12-300mm, thickness 4-60mm, cross section is rectangular and with pure edge of steel. Flat steel can be finished steel, or can be used as the blank of welded pipe and thin slab for laminated sheet rolling. Section steel is one of the four major steel products (plate, tube, mould, wire). According to the section shape, the section steel is divided into simple section steel and complex section steel (deformed steel). The former refers to the steel, round steel, flat steel, angle steel, six angle steel; the latter refers to the I-beam, channel steel, steel, steel, steel frame bending etc..
Q:What is the quota for the flat steel used in the lightning belt -40*4?
I have also checked the quota, but there is no flat steel laying in the lightning protection and grounding device of the electrical installation of the second book. I usually refer to the grounding bus.
Q:Do lightning protection, lead out of the galvanized round steel, flat steel needs to be inspected?
The corrosion resistance of cold galvanizing is not as good as that of hot-dip galvanizing. It is used as lightning protection and grounding material. It is corroded quickly, and the grounding resistance is raised rapidly. It exceeds the required resistance.
Q:Is the laying of a 40X4 flat steel for fire fighting metal trunking?
The angle between the bridge is connected or welded together by rivets, but in accordance with the relevant provisions of the State Grid, not admit that these are valid connection. At the same time in order to protect the ground, must have a grounding cable connection between all seams of metal objects, so that it can recognize all of its bridge is connected to one end, through one or a plurality of total grounding grounding.
Q:What is the difference between 60X6 and 50X4 flat steel in grounding?
There are differences, mainly based on the local geological conditions, the purpose is to meet the requirements of grounding resistance.
Q:What are the standards for the use of galvanized steel angles and flat steel for grounding?
(1) grounding wire is generally made of 40mm * 4mm galvanized flat steel.(2) galvanized steel or angle steel for earthing body. The diameter of the steel pipe is 50mm, the wall thickness of the pipe is not less than 3.5mm, and the length is 2 to 3m. Angle iron shall be 50mm * 50mm * 5mm.
Q:Earthing flat steel and earthing main line
The flat steel is connected to the ground system, and the grounded line is connected to the protected equipment
Q:How is three grade steel connected to ground flat steel?
HRB400 can be directly welded by hand arc welding with Q235 flat steel into electrical circuit. (I have done two sets of tensile tests last year, qualified).
Q:The technological process of flat steel
The working principle of precision steel production process of flat steel finishing machine is cold flat bad hair with two sets of upper and lower staggered leveling wheel thickness pre leveling and final leveling; with a pair of oppositely disposed finishing wheel in the width direction of extrusion, the width is compressed and reaches the expected parameters and the amount of compression can be adjusted; with 5 aspects of straightening straightening wheel arrangement of the staggered width. This system is mainly composed of a control box, finishing roller, pre leveling unit, finishing unit, straightening unit.
