"Small city" by hunan yuanda technology corp. 's broad can build a company built, 57 floors built 19 days, creating the contemporary architectural marvel.Height of 200 meters and a building area of 200 square meters, including 3.6 kilometers of pedestrian street, 19, 10 meters high hall, can accommodate 4000 people in the workplace and 800 homes.


"Building blocks" house, "production" on the assembly line, can reduce construction waste and dust pollution of prefabricated buildings will be in the future in China.
It is in this big background, the state encourages the introduction of steel structure housing, digestive steel energy as much as possible for the residents to build high quality living environment at the same time good residential patterns.Steel structure residence in North America, has more than 30 years of development history, gradually formed a very mature system of construction, in recent years has been widely promotion and use.Some people worry that the structure of the house is not suitable for development in China, it's not.First take a look at the advantages of this structure residence, just know whether steel structure housing can take root in China.
First of all, the steel structure modular construction conform to the requirements of the green, environmental protection, energy saving;Second, the steel structure residential building materials can be recycled, it is known to all concrete completion of residential if demolition almost all materials will cause waste, not much use value again.And the steel structure housing is different, no matter how many years will not occur corrosion or wear and tear, to increase the utilization rate of recycling to eighty percent.Third, the construction of the steel structure building much faster than concrete structure buildings, a 200 - square - metre villa need only about thirty days;Fourth, the steel structure building modelling richer, function more powerful;In addition, the steel structure modular construction for longer service life;


  • And the state science and technology, high strength and high corrosion resistance of building fastener manufacturing
    Fasteners are small, but since construction overall xing



      Jiaxing UNITEK mechanical technology co., LTD. Is the first domestic manufacturing high strength and high quality architectural stainless steel fasteners production enterprise, broke the situation of such products long-term dependence on imports.Companies with high hardness, high strength martensitic stainless steel (SUS410) drlling self-drilling screw, self-tapping screw, high strength stainless steel bolts engineering classes give priority to dozen of product construction fasteners, products widely used in domestic and foreign high-end steel structure building, outdoor facilities and subway, tunnel, highway, power grids, automobile, shipbuilding and other industries;The capital airport T3 terminal, CCTV tower, Beijing south railway station, Shanghai hongqiao high iron, 2022 Asian games stadium in hangzhou, shougang Beijing Olympic sports center, Shanghai Disney tang steel, baosteel zhanjiang iron and steel, and so on domestic thousands of landmark building has a close bond technology products in their lives.Products with high strength, good corrosion resistance, safe, diverse and features such as saving.

  • Composite metal drlling self-tapping screw - one hundred years of life building fasteners!

With the constant improvement of the construction requirement at home and abroad, the state science and technology research and development team after 10 years of efforts, finally developed a can be widely used in all kinds of construction, 100 years of service life of composite metal drlling self-tapping screws.This screw thread lock section and head for austenitic stainless steel, but tapping and apex drill tail part adopts martensitic stainless steel SUS410, then through a special surface treatment after heat treatment, penetration and rust corrosion resistant performance are beyond the current widely used in various types of imported products.

Compared with imported screw, or the state science and technology of composite metal the performance characteristics of self-drilling screw with tapping screw is as follows:

 

1, screw the attack rate faster, more energy
Drlling tool bit by SUS410 material, after special heat treatment, blade surface hardness of the cutting tools with more HV580, core hardness is between HV350-450, strong performance beyond alloy steel cutter, coupled with the unique drlling tool bit shape design, achieve the result of the effort and the most rapid construction, foothold on altitude or difficult construction, energy and the effect of reducing the burden.


2, applicability, can penetrate the stainless steel plate
SUS410 stainless steel has excellent "red hard" performance, under the 550 ℃ can still maintain strong tapping drilling capacity, thus can successfully penetrate up to 18 mm stainless steel plate or carbon steel;And alloy material in the temperature over 250 ℃, the hardness has dropped sharply, it is difficult to penetrate thick stainless steel plate or steel plate, even if successful penetration, the tapping and fastening work hard to complete.


3, strength and corrosion resistance, perfect union of acme corrosion resistant effect
/ SUS304 SUS316 austenitic stainless steel materials such as excellent corrosion resistance, SUS410 martensitic stainless steel corrosion resistance, although slightly inferior, but is much stronger than carbon alloy steel, strength and hardness is superior to the latter, screw and the state science and technology, special surface treatment for economic co-operation and development (such as zinc, aluminium powder metal coating processing), after assembly related to construction, threaded portion and bare head of SUS304 / austenitic stainless steel SUS316, resistant to wind and rain erosion and acid and alkali environment, sustainable in a general neutral interior environment is safe and effective service more than 80 years.
