Machining

In 1995, Yieh United has opened its metal hardware processing department, which is near electroplating factory in Hebei Province.
Experienced in this area for many years, we have developed many customers in America and Canada.
In 2012, we have induced casting machine to produce construction spare metal parts.
Currently, we have developed into a comprehensive metal hardware processing factory.

  • Descriptions:
    Reducer is a kind of fitting that be used for reducing piping size. There are 2 types reducer as follows:
    a. Concentric reducer: have a central axis (centerline) of the section between the large and small.
    b. Eccentric reducer: the central axis has a different (offset) between a large section and small.
    Concentric reducer is most commonly used and often eccentric reducer used in piping in about pump and pipe rack area.

    Size:
    Seamless Pipe Reducer: 1/2″~32″ DN15~DN800
    Welding Pipe Reducer:6″~60″ DN150~DN1500

    1. Hardware Processing

      1. Washers/gasket

       

      washer and gasket- yieh united corporation

      Beveled Washers are a type of flat washer that is either square or circular with one surface consisting of a sloping angle. Generally used in structural applications, beveled washers fasten bolts through I-beam flanges to generate a parallel surface.

      Specifications:
      1.Grade: A2, A4
      2.Size: M3-M100
      3.Finish:plain, zinc plated, hot dip galvanized
      4.Material:Carbon steel, stainless steel
      5.Packing: Standard export packing or According to customer's requirement

      material stainless steel,carbon steel ,copper
      surface treatment black ,passivating,according to your requirement
      Application fields construction industry,furniture fields and other public equipment
      1. B. Bolt

      U bolt907_ hardware
      U Bolts are used heavily in building and construction. The u, or bent, shape of the bolt keeps it firmly in place, adding security and stability to the join. U bolts are used as framing fasteners and anchors for foundations and roofs, pipe and conduit holders and bolts for motor and engine shaft components.

      Standard & Custom U-Bolt Materials
      Our U bolts are available in steel alloys, carbon steel and stainless steel alloys. Zinc, Cadmium and hot dipped galvanized coatings are offered for custom coating and finishing. Our cutting and chamfering services will customize your U bolts to meet the tightest tolerances so that your finished product meets your exact requirements.

      2. Steel Fence

      Steel Fence

      Specification:
      1. Heavy duty Crimp top security fence in Black color
      2.Width 2400mm x Height 1800mm Crimp top diamond shape
      3.40x40x1.6mm top rail, 25x25x1.2mm Verticals
      4. There are 17 vertical pickets 20x20mm with diamond crimped on top.
      5. Gap in between the pickets is 110mm
      6. 60x60x2mm thick post - these are 3m long each not 2.6m long as others supply.
      7. Normal fence powder coated brackets
      8. Security fence brackets ( powder coated )
      9. Caps for 60x60 posts (powder coated )
      10. Phosphate treated before powder coating (Very Important) - Not many suppliers even know about this process.
      11.All panels are fully protected

      Product detailed introduction
      1) Our panels are made out of thicker material top and bottom rails 40x40x1.6and 25x25x1.2 for all-verticals
      2) Gap in between the verticals is 110mm compared to wider gaps with others.
