Welded steel pipe, also known as welded pipe, is produced by forming a steel plate or strip through crimping and welding. The production process of welded steel pipes is relatively simple, resulting in high production efficiency and a wide range of specifications. It requires less investment in equipment compared to seamless steel pipes. However, it is important to note that the general strength of welded steel pipes is lower than that of seamless steel pipes.

Rebar, commonly known as hot rolled ribbed bar, is a type of steel bar. The grade of ordinary hot rolled steel bar is determined by its minimum yield point and is denoted by HRB (Hot Rolled Bar) followed by a numerical grade. The letters H, R, and B represent hot rolled, ribbed, and bars respectively. Rebar can be classified into different categories based on its strength, such as HRB300E, HRB400E, HRB500E, HRB600E, etc. The thread specification range of rebar is generally 6-50mm. We usually involve more are 8mm, 10mm, 12mm, 14mm, 16mm, 18mm, 20mm, 22mm, 25mm, 28mm, 32mm, 36mm, 40mm and so on. National allowable deviation :6-12mm deviation in ��7%, 14-20mm deviation in ��5%, 22-50mm deviation in ��4%. Generally, the fixed length of rebar is 9m and 12m, among which 9m long thread is mainly used for normal road construction and 12m long thread is mainly used for bridge construction.

Wire rod refers to rolled steel with a circular cross-section, typically ranging in diameter from 4mm to 16mm. It is commonly available in the form of coils or bundles. Wire rods are produced using various materials such as steel, aluminum, copper, and non-ferrous alloys. There are numerous types and varieties of wire rods available. Carbon steel wire rods are categorized into two main types: medium and low carbon steel wire rods, which are often referred to as soft wire rods, and medium and high carbon steel wire rods, which are commonly known as hard wire rods.

Sheet piles are structural elements that consist of interlocking segments with concave profiles (grooves) forming alternating concave and convex walls. These sections are commonly manufactured using steel or other metals, and the presence of grooves enhances their resistance to bending. Steel sheet piles are categorized into three main types: straight steel sheet piles, U-shaped steel sheet piles, and Z-shaped steel sheet piles. Each type has its own unique design and structural characteristics, allowing them to be utilized in different applications and soil conditions.

Angle steel, commonly known as angle iron, is a carbon structural steel extensively used in construction. It is characterized by its long strip shape with two sides perpendicular to each other, forming a simple section profile. Angle steel is divided into two categories: equal angle steel and unequal angle steel. The production of angle steel starts with low carbon square billets as the raw material. The finished angle steel can be in a hot-rolled, normalized, or hot-rolled state. Angle steel is versatile and can fulfill different stress requirements in structures, serving as a connection between components. It finds wide application in various building structures and engineering projects, including beams, bridges, transmission towers, lifting and transportation machinery, ships, industrial furnaces, reaction towers, container racks, and warehouses.

I-beam, also known as a steel beam or universal beam, is a long steel structural member with an I-shaped cross-section. There are two main types of I-beams: hot-rolled I-beams and lightweight I-beams. I-beams can further be categorized into ordinary I-beams, light I-beams, and low alloy light I-beams. The wings of ordinary I-beams and light I-beams gradually taper from the root to the side at a certain angle. The designation of an ordinary I-beam or light I-beam is indicated by the numerical value representing its waist height in centimeters. I-beams find extensive use in various applications, including building structures, curtain wall engineering, mechanical equipment, and vehicle manufacturing. Their structural strength and versatility make them suitable for supporting heavy loads and providing stability in construction and engineering projects.

Channel steel is a long strip of steel with a fluted section. It is a type of carbon structural steel commonly used in construction and mechanical applications. Channel steel has a complex section with a groove shape. It finds its primary usage in building structures, curtain wall engineering, mechanical equipment, and vehicle manufacturing. Channel steel is often used in conjunction with I-beams. Channel steel is divided into two main types: ordinary U-steel and light channel steel. The specification for hot-rolled ordinary channel steel typically ranges from 5# to 40#. On the other hand, the specification for hot-rolled flexible channel steel is typically determined through an agreement between the purchaser and the supplier and generally falls within the range of 6.5# to 30#.

Roof panels are specifically designed panels capable of directly bearing roof loads. In the case of roofing and exterior walls made from aluminum-magnesium-manganese alloys, they commonly undergo a pre-roll coating (Coil Coated) process. This process offers several advantages, including precise color difference control, uniform paint film application, high quality stability, and environmental friendliness. By utilizing the pre-roll coating process, the resulting roof panels exhibit excellent aesthetic appeal, consistent paint coverage, reliable quality, and adherence to environmental standards.

Galvanized corrugated sheets are building materials created by subjecting hot-dip galvanized mild steel sheets to a cold rolling process, resulting in a linear corrugated pattern. The corrugations, which consist of ridges and grooves, enhance the bending strength of the sheet in a direction perpendicular to the corrugations. The corrugated design of galvanized corrugated sheets provides multiple benefits. Firstly, it increases the overall strength of the sheet, enabling it to withstand bending and other stresses. This enhanced strength contributes to the longevity and reliability of the sheets, ensuring years of dependable utility. Additionally, the ridges and grooves improve the sheet\'s resistance to external forces such as wind and impact.

Tinplate Coil, also known as electroplated tin steel sheets, refers to cold-rolled low-carbon steel sheets or strips that are coated with commercial pure tin on both sides. Tin serves as a protective layer, preventing corrosion and rust. This material combines the strength and formability of steel with the corrosion resistance, solderability, and aesthetic appearance of tin. Tinplate Coil possesses several advantageous properties, including corrosion resistance, non-toxicity, high strength, and good ductility. It offers excellent protection against corrosion while maintaining a safe and non-toxic packaging material. Tinplate packaging has a wide range of applications in the packaging industry due to its ability to provide effective sealing, preservation, light-proofing, durability, and unique metal decoration charm.
