Roller shutters

Roller shutters have many applications, including doors for vans, garages, kitchens, schools, prisons, and warehouses. In some parts of the world, roller shutters are subsidized by local governments. In areas that are frequently exposed to inclement weather, roller shutters are used as a method of insulation, can protect windows against hail damage, and can be made to withstand high wind. If you are a supplier of roller shutter, you have a so big market. As manufacture of roller shutter door making machine, we are responsible for you and our machines, the quality must be best.

Wall Angle Bead Profile Roll Forming Machine

Wall angle bead profile roll forming machine can used to produce angle beads in batch. It is fully automatic. We can control the angle beads length through the PLC controller. If you need the training, we can arrange our engineers to teach you.

There is a machine of wall angle bead profile roll forming machine.

wall angle bead profile roll forming machine

For the wall angle bead, you can know more information in the followings.

The features of metal wall angle bead

1. The metal corner wall angle bead is made of high quality galvanized material on both sides to prevent aging, corrosion and fire, and effectively prevent rust.
2. The precise acute angle dimension design of the metal corner strips avoids the concentrated stress when the corners are impacted, and evenly distributes the external forces to the peripheral edges, effectively protecting the sunken corners from damage.
3. Two types of metal corner strips, punching and expansion, not only facilitate nailing but also make the gypsum board or other adhesive materials in the corner strips more firm.
4. The construction of metal corner strip corners does not rely on wood strips. Primary plasterers can also make perfect corner lines, shorten construction time, and effectively reduce construction costs.

The usage of wall angle bead

The wall angle bead can form a straight edge on the ridgeline of the plasterwork to resist cracking or cracking, and protect and reinforce the most vulnerable part of the stucco. The net wing can be firmly anchored into the plaster on either side of the ridgeline. The full depth of the mud. The corner net is very important for stucco decoration because the corners of the stucco are most likely to be damaged during construction and completion of use, and it can save a lot of time because of its easy construction.

The difference between C purlin and Z purlin

With the increasing popularity of steel structures, the use of C purlin and Z purlin has also increased. What is the difference between the two? Here we will focus on the differences between c purlin and z purlin.

C Z purlin

1. The angles of Z purlin and C purlin are different. The C purlin is 90 degrees and the Z  purlin is less than 90 degrees. Therefore, when using a screed on a certain slope, it is necessary to consider the angle of the purlin in combination with the knowledge of the rake, and the slope is large and the Z purlin can be used. Take full advantage of its bending performance.

2. Compared with the Z section, the mechanical properties of the C-section and the Z-section are different, and the connection to the steel frame is mostly bolted. The calculation must be based on simple considerations. Therefore, from the aspects of stress state, structure and calculation results, the latter is more reasonable. Therefore, in addition to the needs of door and window openings and other special nodes, Z-sections should be preferred.

3. when the roof slope is small, the modulus of flexural section of Z purlin is slightly larger than that of C purlin, but the difference is not significant. When the roof slope increases, the modulus of flexural section modulus of Z purlin symmetrically increases in the vertical direction. Big. Therefore, Z purlins are suitable for roofs with large slopes.

4.  for the wall, the choice of Z purlin or C purlin does not make much difference, if the purlins want to make a continuous component, the best Z purlins, because of its convenient lap.

Based on the difference between C purlin and Z purlin, you should consider which situation is more suitable to use the C purlin or Z pulin.

Specification and quality problems of light steel keel

Partition keel refers to partition light steel keel, which are used as decoration by most families. In the followings, i will introduce some specification and quality problems of light steel keel to you.

Specification of light keel

The thickness of light steel keel is from 0.4 mm to 2 mm. In general, most people choose light steel keels when using paper plaster ceilings. Thin gypsum board using thin light steel keel, gypsum board thicker with a thicker light steel keel. There are two types of galvanized keel, cold galvanized and hot galvanized. Hot galvanized prices are higher.

partition keel

Should pay attention to the quality problem

1.Wall shrinkage deformation and board surface cracks: The reason is that the vertical keel tightly up and down the keel, did not allow expansion and contraction, more than 2 meters long wall does not control the deformation joints, resulting in wall deformation. A 3 mm gap should be left so that distortions and cracks due to temperature and humidity effects can be reduced.

2. Light steel skeleton connection is not strong, because the local node does not meet the construction requirements, the installation of local nodes should be strictly in accordance with the provisions of the map. Pinning spacing, location, connection method should meet the design requirements.

3. Wall coverings are uneven, and most of them are caused by two reasons: one is the lateral misalignment of the keel, and the other is that the thickness of the plasterboard is not uniform.
