Welded steel mesh, a new form of reinforcement, is especially suitable for large-area concrete engineering.

3The pipeline shall be positioned according to the drawing design, and the pipeline support shall be prefabricated according to the site conditions. Hang the wire from the th floor down and fix the support.

aChicagoI-beam is mainly divided into ordinary I-beam, light I-beam and wide flange I-beam. According to the height ratio of flange to web, it is divided into wide,Products Show that is,U.S.A022cr17ni12mo2 seamless pipeHow is it stored the corresponding height is -. At the same height the light I-beam has narrow flange, thin web and light weight. Wide flange I-beam, is characterized by two parallel legs and no inclination on the inner side of the legs. It belongs to economic section steel and is rolled on four high universal mill, so it is also called "universal I-beam". Ordinary I-beam and light I-beam have formed national standards.

Sulfur is a harmful impurity in steel. Steel with high sulfur content is easy to embrittle during pressure processing at high temperature, which is usually called thermal embrittlement

VAtletico Granadilla First, we can clean the outer surface of the welded pipe with solvent or emulsion. This method is very effective for cleaning the oil stain, dust and other organic matters on the surface of the welded pipe.

Rw Manganese: it can improve the strength of steel, weaken and eliminate the adverse effects of sulfur, and improve the hardenability of steel. High alloy steel (high manganese steel) with high manganese content has good wear resistance and other physical properties

Galvanized pipes shall be stored in dustproofto keep clean and new . As a professional manufacturer of galvanized pipe,Products Show we have produced galvanized pipe products for many years. Welcome friends who need to buy.


Polished stainless steel pipes shall be subject to internal inspection and strict manual selection by the steel pipe quality inspector through metal detector (or hydrostatic test), and qualified products shall be packaged and delivered.

qI-beam has the dual properties of high hardness and toughness materials. Compared with other engineering wear-resistant materials in China, such as various alloy steel plates, cast wear-resistant plates, cast stones, rubber, polyurethane, etc., it has irreplaceable comprehensive excellent properties.

QSpeed up the construction progress: weld the mesh with reinforcement to allow the rapid construction of the project. The required laying of welded steel bars is provided, so concrete can be poured,Products Show steel cutting, stitching,U.S.A022cr17ni12mo2 seamless pipeHow is it stored etc. and the arrangement can be strengthened. ? saving construction time? The construction progress is greatly accelerated and the construction period is shortened.

Seamless pipe is resistant to corrosion, alkali, salt and atmospheric environment, high temperature impact and fatigue, does not need regular maintenance, and the effective life is more than years;


Galvanized pipe has excellent corrosion resistance. Compared with traditional steel, its application life is longer. Secondly, this kind of pipe has strong resistance to baking. In case of critical situation,Reinforcement, galvanized pipe, seamless pipe, welded pipe, alloy pipe, I-beam-Shandong Kaiwen metal material Co., Ltd it will not lead to the collapse of building structure in a short time. In addition, this kind of pipe also has a practical advantage, that is, and the operation efficiency has been greatly strengthened. In this regard, it is not difficult to understand why the galvanized pipe is so favored by various construction units.

Pursuit of excellencetMost of the original bridge decks lack a stable and solid base course with poor integrity. It is necessary to clear the original bridge deck, excavate part of the gravel cushion (if it is non gravel filler, replace it with gravel filler and tamp it), and then pave cement stabilized gravel base course on which reinforced concrete bridge deck is poured. The longitudinal reinforcement and transverse reinforcement of the reinforcement mesh of the bridge deck pavement form a network structure, so it has good bonding and anchorage with the concrete, and the load can be evenly dispersed, which obviously improves the performance of the reinforced concrete structure. According to the practice test, the welded reinforcement mesh laid on the road can reduce the occurrence of cracks than the manual binding mesh.

NGB No. I-beam is in height, in leg width and in waist thickness.

They do not need to protect them from mechanical damage.

mChicagoIn hardware, you can choose an incomplete performance outside the product. Some construction experts claim that if there is a mechanical effect on these products, they are not suitable. At least this product is impossible.

gLThe smooth of steel pipe is mainly through tension reducing, which is a continuous rolling process of hollow base metal without center and tip. Under the condition of ensuring the capillary welding quality, the whole welded pipe is heated to more than ℃ by the welded pipe tension reduction process, and then rolled to finished pipes with various outer diameters and wall thicknesses by the tension reduction machine ( times in total). The fluid pipes produced by developed countries in the world have adopted the welded pipe smooth process in a large number of boiler pipes. With the development of society, Domestic hot welded pipe has gradually formed a situation to replace smooth pipe.

When the mesh reinforcement on both sides of the beam is different, the reinforcement on both sides extends into the beam, and the reinforcement anchorage length is required.
