Physical performance testing laboratory

Wire drawing line

Our state-of-the-art production line is composed of an Italian large-diameter straight wire drawing machine, several pieces of small and medium-diameter straight wire drawing equipment, as well as several pieces of wet wire drawing machines.

Here is the wire rod payoff. We operate several pieces of straight wire drawing machines simultaneously. Wires are repeatedly drawn to meet customer specific requirements. This production line can manufacture cold-drawn steel wires in diameters ranging from 0.6mm to 12mm.

Heat treatment workshop

Large-diameter galvanized wire production line

A single shaft of the steel wire pay-off unit weighs up to 2 tons.
Annealing is performed at a specific temperature after the drawing of steel wires. This allows us to achieve the required mechanical properties before galvanization.
Cleaning is carried out in four stages, which means the surface of the steel wire is cleaned with alkali, hot water, hydrochloric acid and cold water.
Cleaning with cold water after the use of hydrochloric acid
After cleaning is done, we put steel wires through the plating, drying and galvanizing procedures.
The galvanized steel wire is subjected to wiping procedure. This allows us to control the quality and weight of the zinc coating. The maximum weight of the zinc coating can reach 850g/㎡.
The steel wire is being taken up after galvanization.
According to customers’ requirements, we can produce different sizes of steel products which are packed on reels.
We also utilize vertical take-up devices to make heavy-duty products as per customers’ requirements. This production line can produce hot-dip galvanized or GALFAN steel wires. These steel wires are comprised of different materials, for example we use: low-carbon steel, medium-carbon steel and high-carbon steel. They vary in diameter from 1.6mm to 8mm. The monthly production capacity reaches 8,000 tons. Typical applications are found in cable armoring, aluminum conductor steel-reinforced cables, fences, screens, etc.

Small and medium diameter workpiece galvanizing line

Copper-coated steel wire production line

Steel wire pay-off
After wire payoff is done, we conduct the annealing process at specific temperature in order to achieve the desired mechanical properties.
The steel wires which have been annealed and cooled need to undergo the alkaline degreasing, rust removal, surface activation as well as copper electroplating procedures.
After copper electroplating is completed, steel wires are cleaned, dried and put through take-up devices. This production line contains 36 take-up devices. It produces copper-plated steel wires which are packed on reels or in Z2 coils. Their diameter ranges from 1.0mm to 5.0mm. These wires are mainly used in production of the inner frame of high-pressure rubber hose. The monthly production capacity reaches 1,000 tons.

Plastic coating line

Steel strand and wire rope production line

We have eighteen production lines available for handling various specifications of steel strands and wire ropes.
Our steel strands and wire ropes are manufactured in diameters ranging from 0.2mm to 160mm.
Steel strand and wire rope production workshop
These machine can produce steel strands and wire ropes in various specifications, such as 1×3, 1×7, 1×19, 1×37, 6×7, 6×19, 6×37, 6×61, 8×19, 8×37, 8×61 with fiber core or steel core etc.
It can also manufacture pre-stressed steel strands in dimensions of 12.7mm and 15.2mm.
We can pack the finished strands or wire ropes in wooden reels or metal reels upon request.
We also can produce the pre-stressed steel strands that are packed in coils.

Pre-stressed steel wire production line

The steel wires which have been cold drawn and galvanized are sent into this equipment. They are straightened under tensile load so as to obtain the axial stress.
Stabilizing is conducted to achieve the low relaxation result.The steel wire that has been stabilized must be cooled down to the room temperature and then coiled. This production line is established for creating low-relaxation galvanized steel wires in diameters of 5mm and 7mm. Main applications are found in prestressed concrete cable-stayed bridges.

We have established several workshops for production of woven wire mesh, crimped wire screen and hexagonal wire mesh. Pictured here is the woven mesh production workshop, where we use more than 100 machines to produce a variety of woven wire mesh in fully automated mode. These facilities have the capacity to handle aperture sizes of 0.003mm-10mm, wire diameters of 0.01mm-2.0mm, and a maximum width of 4 meters.
We maintain an ample inventory of raw materials for woven mesh, which ensures the product variety and timely delivery of goods. We can produce the
woven wire mesh in different materials, such as galvanized mesh, stainless steel mesh, pure copper mesh or pure silver mesh.

Stainless steel woven wire mesh is among our range of products. We can offer various types of weaving methods, including: plain weave, twilled weave,
plain Dutch weave, twilled Dutch weave, reverse plain Dutch weave and reverse twilled Dutch weave. Raw materials include: stainless steel 304, 304L, 316 and 316L. All the length, width and aperture size can be customized upon request.

The wire mesh that has been flattened will undergo quality testing. We put every piece of woven wire mesh through the defect inspection, length/width
measurement and the sampling of meshes. Test results are all recorded.

1. Twelve CNC machines are employed to produce the perforated mesh in more than 200 opening patterns and various sizes.
2. Optional opening patterns: rectangular hole, square hole, diamond hole, round hole, hexagonal hole, cross hole, triangular hole, pattern hole, irregular hole, etc.
3. The opening pattern can be created according to customer’s drawings.
4. Bending is available upon request.
5. Thickness of the conventional mesh: 1mm-10mm
6. Thickness of the micro-porous mesh: less than 0.5mm

Steel nail production line

Approximately 300 advanced machines are operating in this workshop. They include a diverse range of high-speed automatic nail making machines and auxiliary equipment.
The automated and continuous production process involves four procedures: steel wire straightening, cold heading, cold extrusion and wire cutting. It is employed to fast produce steel nails in various specifications.Our automatic thread rolling machine can fulfill various customers’ nail surface requirements. In this workshop, we can produce nails with a variety of surface treatments, e.g.,
smooth shank nails, screw shank nails and ring shank nails.
