Detailed Product Description

Iron productsproducts have strict manufacture processes in designs, material selection and manufacture 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 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 surface, the surface should not crack at the bend parts after bent 180 degrees flexural centre diameter, and steel bar surface should not crack , scar over or collapse.

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

Forging stock blanking, forging stock heating, roll forging for blank, stamp forging to certain shape, trimming cut, intermediate 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 hardnes 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 level, straight, smooth, and the arch should be smooth, and without twist, and the flower mould should be smooth with the jointing has to be artistic and firm. The welding line must be neat and firm. Flower mould must be in proportion with the same model number shouber 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 structure. Any burr occurred after forged must be post be polished before bending. Theing. Theing. The grad distance istance must be less than 110mm by any gate, railing, staircase, handrail or iron windown windown windown windown window without any declare of special demands as per safety standards. Sample plate must be made to be confirmed befored before large batch production. The on. The si. The siz The size and jointing technology of iron art products should be tested by quality inspety inspector. Manufacture size and the size required by design are allowed to make a deviation of 1:1000 according to diffeto different products.

Hot galvant galvanize technology: every piece can be welded all together should be welded before hot galvanize and it is nott is not allowet allowet allowet allowet allowed allowed to weld after hot galvanize without without any special situation. For hot galvanize products, wducts, weep hole should be opened from the private posiate posiate position of the tube to ensure air flow smooth for molten Zinc and acid wasacid wash. To prevent the sealing of ting 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 weldiof weldiof welding directg directly. The thickness of cold galvanizing layer is 5-1r is 5-15um, can keep the product out of rust for more than 2 years. But hot But hot galvanize technology, nology, the best of all in all in this field, iron art decoration products areucts areucts are put into about 455 degrees degrees Zinc ba Zinc bath with Zinc rare ec rare earth alloy and billet aluminum, isinum, is used by our Shou Je Shou Jee iron art decoration corporation. The thickness of tess of the hot galvani galvanize layer is above 65μm, even come up to 100μm. The advantages of hot galvanizealvanize is thze is that it has it has it has goo has good coverod coverin covering power, dense galvanize layer and without any organic matter. The weather-resistant mechanism of Zinc in Zinc includes mechanical protection and ion and electrochemical protection: the surface of hot galvanize layer has ZnO, Zn(OH)2 , ZnCO3-2Zn(OH)2-H2(OH)2-H2OOH)2-H2O in atmospheric corrosion rrosion condition, which slow down the rusty of Zinc to a certain extent. This protective layer called white rust can form an form a new layer whlayer whlayer whlayer while destroyed.  Weather-resistant power to base metbase metallic iron of hot galvanizealvanize technol technology is much better than that of cold galvanizialvanizing, and hot galvanizing can keep the products out of rust ov rust overust over 50 years.

Pa;p>Painting ainting technology: gloss of the painting divided into: light, matte, semi-matte, light divided into: touches, semiflat, dead luster. The brighter the pai the paintings are, the more ageing-resistant they are. The drying functions are divided into surface dryiace drying and hardand hard drying with suitable moiable moisture of 65 percent percent.percent. Each kind of painting makes different drying time, to ensure the strength of adhesive force and to make it look the same as new, we control control control the drying time of followinfollowing:

Nitryl lacquer basic painting surting surface drying time is 0.2 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 time is 0.5 hour, hard dry time is 8 to 10 hours

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

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

Alcohol acid gulf red finish coat surfaat 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
