Iron products have strict manufacture processesrocesses in designs, maters, material selection and manufacture craft&l craft

Design: in charge of our full-experiment designer­-Lion Ren, who has been in this field for 15years and held the position of design director of a Hong Kong company

Material selection: we select high grade fine steel (P less than 0.035 percent,S less than 0.030  percent)cold nt)cold drawn steel which is in line with ISO9001 international standard. Each steel material is strict selected with the surface neat and smooth, the separation angle should be no less than 45 degrees between cross rib and steel bar sul bar surface, the surface should not crack at the bend parts afterts after bent 180 det 180 degrees flexural centre diameter, and steel bar surface should not crack , scar over or collapse.

Forging Technology: to force pressue pressure on the planchet by the metal forming machinery (air forging hammer and mechanical press ) so as to make it plastic deformation to achieve the certain forgeable pieable pieable pieces in diff in different shape or size. Processes as below:

Forging stock blanking, forging stoging stock heating, roll forging for blank, stamp forging to certain shape, trimming cut, intermedintermediatermediate inspection, inspection of the size and surface blemish of the forging pieces. Forging heat-treatment to remove forging stress and improve metal machinability ;  sweeping is used to wipe surface oxidation; the exterior appearance and hardness should be checked commonly

Welding Technology: our lofting master draw the same picture as the design in 1:1 proportion with the product. Our past master jointing worker then weld the iron products already bent to shape all together. The product should be ould be leld be level, straightstraight,traight, smooth, and the arch should be smooth, and without twist, and the flower mould should be smooth with the jointingjointing has to be artistic and firm. The wm. The welding line must be neat and firm. Flower mould must be in proportion with the same model number should be the same and coincide completely. Any workpiece cut by plasma cutting or not easy to polish must be polished before gang welding. Accessory pieces must be forged or polished before bent in shape, then welded with main iron art structt structure. Any burr occurred after forged must be polished before bending. The grad distance must be less than 110mm by any gate, railing, staircase, handrail or iron window without any declare of special demands as per safety standards. Samrds. Sample plate must be made to be confirmed before large batch production. The size and jointing technology of iron art products should be tested by quality inspector. Manufacture size and the size required by design are allowed to make a deviation of 1:1000 according to different products.

Hot galvanize technology: every piece can be welded all together should be welded before hot gd be welded before hot galvanize and it is not allowed to weld after hot galvanize without any special situation. For hot galvanize products, weep hole should be opened from the private position of the tube to ensure air flow smooth for molten Zinc and acid wash. To prevent the sealing of the gate go out of shape, the sealing must be welded after hot galvanize. All products should open up an angle, the two angles welded together in stead of welding directly. The thickness of cold galvanizing layer is 5-15um, can keep the product out of rust for more than 2 years. But hot galvanize technology, the best of all in this field, iron art decoration products are put into about 455 degrees Zinc bath with Zinc rare earth alloy and billet aluminum, is used by our Shou Jee iron art decoration corporation. The thickness of the hot galvanize layer is above 65μm, even come up to 100μm. The advantages of hot galvanize is that it has good covering power, dense galvanize layer and without any organic matter. The weather-resistant mechant mechanism of Zinc includes mechanical protection and electrochemical protection: the surface of hot galvanize layer has ZnO, Zn(OH)2 , ZnCO3-2Zn(OH)2-H2O in atmospheric corrosion coosion condition, which slowich slow down the rusty of Zinc to a certain extent. This protective layer called white rust can form a new layer while destroyed.  Wenbsp; Weather-resistant power t power to base metallic iron of hron of hot galvanize technology is much better than that of cold galvanizing, and hot galvanizing can keep the products out of rust over 50 years.

Painting technology: gloss of the paintin painting divting divided divided into: light, mlight, matte, semi-matte, light divided into: touches, semiflat, dead luster. The brighter the paintings are, the more ageing-resistant they are. The drying functions are divided into surface drying and hard drying with suitable moisture of 65 percent. Each kind of painting makes different drying time, to ensu to ensure the strength of adhesive force and to and to make it look the same as new, we control the drying time of following:

Nitryl lacquer basic painting surface drying time is 0.2 is 0.2 hour, 2 hour, hard dry time is 1 hour

Bi-component epoxy primer painting surface drying time is 0.5 hour, hard dry time is 24 hours

Bi-component epoxy zinc rich primer painting surface drying timying time is 0.5 hour, hard dry time is 8 to 10 hours

Acrylic dilute acid air dry par dry painting surface drying time is 0.5 hour, hard dry time is 4 hours

Bi-componentomponentomponent acrylic finish coat surface drying time is 0.5 hour, hard dry time is 8hours

Alcohol acid gulf red finish coat su coat su coat surface drying time is 2 hour, hard dry time is 24 hours

Red lead gulf red finish coat surface drying time is 4 hour, hard dry time is 24 hours
