Galvanized bolts are bolts that have undergone a galvanization process, which involves coating the bolts with a layer of zinc to provide protection against corrosion. The galvanization process creates a protective barrier that helps prevent the bolt from rusting when exposed to moisture and other corrosive elements.
We produce and sell steel pipes, carbon steel pipe, GI pipe, carbon steel pipe , SS pipes and Spiral steel pipe in long term.
Our factory have plenty of steel in stock and customers can find the right products.
Rock bolts are commonly used in civil engineering and mining to reinforce and stabilize
rock masses. A rod or bar is inserted into a drilled hole, which is then grouted in place using
cement or resin. FRP Rock bolts withstand tensile forces and evenly distribute load,
eventually increasing overall strength. They control rock movements, reduce deformation
and prevent collapses.
We are mainly for customers to provide a variety of pipelines. The pipes we sell include plastic pipes, PVC pipes, HDPE pipes, LDPE pipes, PE pipes, PPR pipes, PC pipes, ABS pipes, PA pipes, PU pipes, hoses, soft tubes, all kinds of plastic granule materials, and recycled regrind materials. Gi pipes, stainless steel pipes, seamless pipes, MS pipes, carbon steel, composited pipes, water tubes, corrugated pipes, fittings, valves, flanges, nuts, and screws. And other environmental plastic and stainless steel pipes
for residential construction households. With meeting international standard quality, the pipes are of different thicknesses, lengths, and applications.
We supply various types of UPVC pipe fittings including welded fittings there are two kinds of welded and nonwelded socket welded and threaded fittings flange fittings

Cast Iron and Ductile Iron tube and fittings PL739
Cast Iron and Ductile Iron tube and fittings can be offered by our comapny to meet different engineering needs.
The difference between ductile iron and gray iron
1. Different chemical composition
Nodular cast iron contains nodular graphite, which can improve its toughness and strength, while reducing brittleness. Gray cast iron contains a lot of carbon, so that its hardness and wear resistance is high, but the toughness is poor.
2. Different organizational structures
The structure of nodular cast iron contains nodular and ferrite, and the distribution of nodular is uniform. While the structure of gray cast iron is mainly ferrite and pearlite, and the distribution of pearlite is uneven.
3. Different performance
Ductile iron has high strength and toughness, and has good corrosion resistance. It is uitable for the manufacture of high load and high pressure parts. The hardness and wear resistance of gray cast iron are high. It is suitable for the manufacture of friction and wear parts.
Application field
Cast iron : because of its low strength and good vibration resistance. It is often used in the production of parts under compressive stress, such as box, base, etc.
Ductile iron : because of its high strength and good toughness. It is often used in the manufacture of parts requiring high strength and toughness, such as crankshaft, connecting rod and so on.
Circular steel pipe is both openings and have hollow concentric sections of steel larger than the surrounding. The specifications of steel pipes are indicated by appearance dimensions and inner diameter and wall thickness, with a wide range of dimensions from very small diameter capillary to large round steel pipe of several meters in diameter. Round steel pipes can be used for pipelines, thermal equipment, machinery industry, petroleum geological drilling, containers, chemical industry, and special uses. It can be divided into seamless, ERW, LSAW, SSAW steel pipe according to the production process.
Pipe fittings are the general names of parts and components that play the role of connection, control, direction change, diversion, sealing and support in the pipeline system. Steel fittings are pressure fittings. According to the different processing technology, it is divided into four categories, namely, butt welding pipe fittings (divided into weld and no weld), socket welding and threaded pipe fittings, flange pipe fittings.
According to the application:
1. pipe fittings for connecting pipes are: flanges, live joints, pipe hoops, clamps, clamps, throat hoops, etc.
2. changing the direction of the pipe: bends, bends.
3. pipe fittings changing pipe diameter: variable diameter (different diameter pipe), different diameter elbow, branch pipe table, reinforcing pipe.
4. pipe fittings with additional piping branches: three links, four links.
5. pipe fittings for pipe sealing: gasket, raw material belt, thread, flange blind plate, pipe plug, blind plate, head, welding plug.
6. pipe fittings for pipe fixing: clasp, hook, ring, bracket, bracket, pipe clamp, etc.
According to the connection :1, welded pipe fittings 2, threaded pipe fittings 3, clamping pipe fittings 4, clamping pipe fittings 5, socket pipe fittings 6, rubber ring connection pipe fittings
According to the material divided into 1, cast steel pipe fittings 2, forged steel pipe fittings 3, alloy pipe fittings 4, stainless steel pipe fittings.
Pipe fittings are widely used in municipal, petrochemical, west-to-east gas transmission, ships and nuclear power.
We deals Galvanized Steel Pipes used for Agriculture and Irrigations, Water Pipeline, Road Barriers. In addition to round pipes, we can also supply galvanized pipes in square and rectangular sections.Hot Dip Galvanized pipes in sizes from 1/2" To 6 OD and in wall thickness ranging from 1MM to 6MM. Our company is specializing in the galvanized pipes, welded pipes and other pipes. Surface hot dipped galvanized, Pre-gavanized, electro galvanized, painted, threaded, beveled, grooved, engraved Usage Scaffolding pipe, Structure pipe, Fence/Door pipe, Furniture, Lowpressure fluid pipe for water oil or gas, Boiler pipe.
