Z Purlins are made using cold-formed or rolled sheets for supporting roof. The flexible shape of these beams facilitates various designs solutions. These purlins are extensively used in huge roofing solutions such as godowns, workshops, industrials sheds and many more. The range is known for saving upto 50% on structural sheet in comparison with hot rolled angles.
Advantages :
Ability to span length
Saving in Steel up to 40%
Fast to erect and easy handling
No side drilling/cutting required
Assured dimensions and straightness
Purlin erection is easier than others
Saving in construction cost up to 30%
High durability, versatility and uniform quality
Close tolerances on sectional dimensions owing to process of cold roll forming
- Q: What does "M" mean?
- M section steel: sectional shape steel like M.
- Q: Does the profile include H?
- In addition, the profiles include: profile steel, including gear ring, horseshoe steel, pole steel, foot plate, shallow channel, small channel steel, T-shaped steel, ball flat steel, send steel, hot-rolled, six angles, etc.. There are also rivets, steel, farm tools, steel, window frames, steel. Cold bending, cold drawn steel and so on.
- Q: What does "BH" mean?
- Section steel is a strip steel with definite section shape and size. It is one of the four big kinds of steel (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: Elastic modulus of section steel
- The elastic modulus of steel is 2.1 * 10^7N/cm L.
- Q: What kind of steel is used in steel columns?
- At present, there are 3 kinds of steel pile commonly used in engineering construction, they are steel pipe column, steel column and steel sheet pile.
- Q: What is special steel?
- Military materialsOther varieties are mainly some special quality profiles. Including hollow steel, oxygen bottles, industrial pure iron, hot rolling, cold heading steel easy to cut steel, D60, S/5A, F18, F11 etc., behind several are. High quality steel is not large, medium and small, round and Fang Gang divided into groups according to specifications from, such as 8-10mm, 11-15mm, 18-20mm, 205-245mm. flat area by large, medium and small flat. Six angle distance is not grouped. But the quality of steel group distance is no substitute for detailed specifications, in the document should be filled concrete specifications. Quality profile specification is simple, the vast majority of round steel. In addition, flat steel, and Fang Gang six chest steel, hollow steel, shaped and so on hot rolling (forging) size deviation of high-quality steel, Fang Gang, the six angle of the ordinary high accuracy and precision of two. And has a more precise cold drawn profile surface size and smooth surface polishing, polishing, but also some After polishing or round processing. The polished surface is exquisite, called steel. High quality profiles are rarely used, mostly through the use of the unit for further processing and after heat treatment, therefore, in addition to chemical composition, but also to ensure the mechanical properties after heat treatment.
- Q: Can the section steel butt joint in the end?
- Docking is usually available.If welding, it is mainly worried that the welding is not strong and the welding stress is too large. The wall thickness of the section steel is thin, and the butt welding itself is the most unreliable. So, in the joint lining board, fillet welded. Attention is paid to reducing stress in the process.Bolt connection also requires lining plate, pay attention to bolt size, quantity and spacing. To calculate whether thin-walled steel itself will be crushing, the solution is solder paste board, and bolt holes.In short, the principle is that the strength of the butt joint is not weaker than that of other parts, and there is no greater stress.
- Q: What are the common types of profiled steel?
- Section steel is divided into two types: simple section steel and complex section steel.Simple section steel: steel, wire rod, square steel, flat steel, six angle steel, triangular, elliptical steel, steel arch steel, etc..
- Q: How to distinguish cold formed section steel and hot rolled section steel?
- Cold-formed steel is one of many varieties of steel in the strip width, under normal temperature conditions after the roll, a group of vertical deformation gradually, to meet the requirements of the use of shape and size, then determine the size of the corresponding shear length. This product is cold-formed steel. Of course, it is also possible to obtain cold-formed steel by stamping, bending or drawing. But the roll bending forming method is suitable for industrial production in large quantities. Its product quality, processing cost and production efficiency are incomparable with other methods, and it is the main production process of cold-formed steel. If the equipment is equipped with welding equipment (such as high-frequency welding, argon arc welding, etc.), it can also produce cold rolled steel with closed section.
