High Quality Nuts

High Quality Nuts are fasteners that are screwed onto a bolt or threaded rod to secure a fastener. High Quality Nuts are generally classified into several types, including carbon steel, stainless steel, and non-ferrous metals (such as copper). High quality nuts are typically hexagonal in shape with internal threads, used to mate with bolts to tighten related components.
High Quality Nuts are categorized by their properties according to national standards (GB), German standards (DIN), international standards (ISO), Japanese standards (JIS), and American standards (ASTM/ANSI). GB, DIN, and JIS standards use “M” to indicate size (e.g., M8, M16), while American and British standards use fractions or “#” to indicate size (e.g., 8#, 10#, 1/4, 3/8).

Hollow Brass Tube

Hollow brass tubes are seamless metal tubes made primarily of copper-zinc alloy.

1. Ordinary Hollow Brass Tubes: Composed only of copper (Cu) and zinc (Zn). Common grades include H96, H90, H80, H70, H68, H65, and H62.

2. Special Hollow Brass Tubes (Special Brasses): Based on copper and zinc, elements such as lead, tin, manganese, nickel, and aluminum are added to enhance specific properties.

– Lead brass (e.g., HPb59-1): Excellent machinability, commonly used in instrument components.

– Tin brass (e.g., HSn70-1, HSn62-1): Strong resistance to seawater corrosion, specifically used in marine condensers and heat exchangers.

– Other: Brass tubes containing manganese, iron, silicon, etc., are used in high-strength or special corrosion-resistant applications.

Honed Steel Tube

Our factory produces and sells various specifications and models of honed steel tube, including precision honed steel tubing, Hydraulic Cylinder Steel Pipe, Hydraulic Honing Steel Pipe, large-diameter honed steel tubes, and small-diameter honed steel pipe.
Our factory has six honed steel tube production lines capable of processing 12-1100mm honed steel tube (for model aircraft and cylinder tubes). The honed steel tubes (for model aircraft and cylinder tubes) produced by our factory typically achieve a roughness of Ra ≤ 0.08μm, correct roundness, and ovality ≤ 0.01mm. This improves surface hardness, eliminates stress-induced deformation, and increases hardness to HV ≥ 4°. A residual stress layer is formed after processing, increasing fatigue strength by 30%, improving fit quality, reducing wear, and extending component life.

Hot Dip Galvanized Steel Coil

Hot dip galvanized steel coil is a common metallic material, produced by hot-dip galvanizing ordinary carbon steel coils. Hot-dip galvanizing is a process that involves immersing a steel coil in molten zinc, coating its surface with a protective layer of zinc. This treatment effectively improves the steel’s corrosion resistance, extends its service life, and significantly improves its appearance and processing performance.

Hot Rolled Steel Coil

Hot rolled steel coil (HRC), that is, hot-rolled steel coil, uses slabs (mainly continuous cast slabs) as raw materials, and is heated and made into strips through rough rolling units and finishing rolling units. The hot steel strip coming out of the last rolling mill of finishing rolling is cooled to the set temperature by laminar flow, and is rolled into a steel strip coil by the coiler. The cooled steel strip is coiled.

Hot Rolled Steel Round Bar

Hot rolled steel round bars are solid, long steel bars with a circular cross-section, formed by high-temperature rolling of steel billets. They are characterized by good hardenability, high hardness, and excellent wear resistance, but their dimensional accuracy and surface finish are lower than those of cold-drawn round bars.

Hot Rolled Steel Sheet Pile

Hot Rolled Steel Sheet Pile (HSP) is a type of steel structural member formed through a high-temperature rolling process, featuring interlocking edges. It can be interlocked to form continuous retaining/water-retaining walls. Main types include U-shaped, Z-shaped, and straight-web type (often called “straight type”).

Hot-dip Galvanized Steel Wire

Hot-dip galvanized steel wire s a type of galvanized steel wire. Hot-dip galvanized steel wire is made from high-quality medium-carbon or high-carbon steel. It undergoes pickling, phosphating, and wire drawing, followed by a hot-dip galvanizing process. The coating thickness ranges from 45 to 300 microns. The zinc layer offers strong adhesion and long-lasting corrosion resistance, maintaining its rust-proof properties for decades in outdoor environments.
