Z beam steel belongs to high-efficiency and economical cutting profile (others include cold-formed thin-walled steel, profiled steel plate, etc.), due to the reasonable cross-sectional shape, they can make the steel perform better and improve the cutting capacity. Different from ordinary I-shaped, the wing embroidery of H-beam is widened, and the inner and outer surfaces are usually parallel, which can facilitate the connection of high-strength screws and other components. Its size constitutes a reasonable series, and the model is complete, which is convenient for design and selection.

The main use products of Z-shaped steel machine can be used as the main force-bearing structure of large and medium-sized industrial and civil buildings, such as the roof load-bearing load of workshops, hangars, exhibition halls, theaters, stadiums, and market flower sheds.

In the case of Z beam steel, the transportation of the unit is convenient. In the case of different Z beam steel purlins, the Z-shaped purlin drops more, and the purlin improves the transportation performance. The Z beam steel can withstand the continuous steel. The transportation performance is better, thus bringing Better to transport purlins this season, for the purpose of packing up materials.

Z beam steel purlin plays an important role in steel structure houses

Since the Z-beam purlin is formed at temperature, the material will be cold-formed. Z beam steel purlins are suitable for cold-formed steel bars such as roofing and wall beams in steel structure engineering. Usually refers to the pull knot strip. The shape of the round steel is to strengthen the purlin, so that the purlin can play the role of strengthening the purlin to a certain extent. Steel structure has many advantages. Although the bulk density of steel structure is relatively large, its strength is quite large compared with building materials.

Common specifications and prices of Z steel purlins

Commonly used steel purlins are Z beam steel purlins, which can be produced with a width of 140-300mm. The thickness of purlins that can be produced is 1.8-2.75mm. Customers can choose appropriate steel purlin specifications and models according to the specific requirements of the project. (including raw material specifications, materials, origin, number of galvanized layers, etc.). The price of steel purlin The price of steel purlin will vary due to the influence of the thickness and width of the steel purlin, as well as the specifications, materials, origin, number of galvanized layers and other factors of the raw materials.

Z beam steel purlins are often used in steel structure engineering

At present, steel structure engineering can be said to be paid more and more attention by people, and the steel structure components are divided in detail. Today, let's talk about steel purlins. Steel purlins are processed by cold bending of hot coils. They have thin walls and light weight, excellent section performance and high strength. Common steel purlins include Z beam steel purlins, C-shaped steel purlins, truss purlins, etc. Steel purlins are the secondary load-bearing components in the roof structural system, which transmit roof loads to the steel frame.

How to lap the Z beam steel purlins more safely

The Z beam steel purlin lap joint is generally a continuous purlin, which bears a relatively large bending moment, and is stronger and firmer. Lap joint is a connection formed by superimposing two steel bars with each other according to certain requirements when the length of the steel bars is insufficient. The basic forms of reinforcement connections are: lashing laps, welding, Z-purlins Horizontal members distributed along the length of the roof, located on the primary rafters, supporting the secondary rafters.

Clearance tolerance for Z beam steel purlins

Under the action of production, installation and initial load, Z beam steel purlin will have certain shape and size deviation. The gap between Z beam steel purlins is mainly for tolerance. As a component connected to the roof bottom plate, Z beam steel purlins need a certain level of flatness!

In the process of making z shape steel, the specifications and dimensions of its steel can be adjusted, and to a certain extent, it has the advantages of high compressive strength, etc. It is widely used in automobiles, railway vehicles, building doors and windows, transportation, shelves, electrical cabinets, Highway guardrails, building steel structures, containers, steel formwork and scaffolding, solar support shipbuilding, bridges, transmission towers, steel sheet piles, cable bridges, agricultural machinery, furniture, storage, rails, keel steel, vegetable greenhouses, pipeline supports, municipal construction and other fields .

The Z beam steel processing machine is composed of a charging frame, a shaping system, a forming system, a correction system, a computer control system, a hydraulic system, a punching, and a shearing system.

The basic process of z shape steel

1. Front-cut type (due to poor molding and large size error, it is rare in the market): unloading → leveling → cutting → punching rib round holes → punching elliptical connecting holes → forming → shaping → straightening → Length measurement.

2. Post-cutting type (commonly used): unloading → leveling → forming → shaping → straightening → length measurement → punching rib hole → punching elliptical connecting hole → forming and cutting.

3. According to the cutting method, it can also be divided into: flying saw cutting, die cutting, electrodeless cutting.

Flying saw cut off

A common machine is (die cutting): Features: fully manual feeding, die changing, automatic punching, length measurement, counting, cutting

status quo

1. Large quantity: Whether it is crude steel output or section steel output, there is a huge amount in the world;

2. Low-end: The main products are concentrated in low-strength and low-quality steel strips, and the high-end market is seriously lacking competitive products;

3. Homogeneity: Based on the large population base in China and the investment concept of the Chinese people, a swarm without any innovation is the characteristic of the industry, and the production capacity is seriously idle;

4. Decentralization: Due to regional restrictions and the impact of logistics costs, the market concentration is extremely low.

The industry as a whole has high investment and low income, resulting in the participation of very little social capital, which further restricts the transformation and upgrading of the industry.
