Detailed Product Description

Iron products 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 ed 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 t crack , crack , scar overcar over or collapse.

Forging Technology: to force pressure on sure on the planche planchetplanchetplanchetplanchet by the metal 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 surface oxiface oxidace oxidation; the exterior appearance andance 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 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 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 polishedpolished before bent in shape, then welded with main iron art structure. Any burr occurred after forged must be polishedpolished before bending. ending. ending. The grad distance must be less than 110mm by 10mm by any gate, railing, stairg, staircasstaircase, handrail or iron window without any declare of special demands as per safety standards. Sample plate must be made to be confirmed before larfore 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 dred by design are allowed to make a deviation of 1:1000 accordi according to different products.

Hot galvanize technology: every piece can be welded all together should be welded before hot galvanize and it is not allowed to weed to weed to weld after hot gal hot gal hot gal hot galvanize without any special situatiosituatiosituatiosituation. For hot galvant galvanize products, weep hole should behould be opened frpened fromned from the prm 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,f shape,f shape, the sealing must be welded after hot galvanize. All products should open up an angle, the le, the two angles welded together in stead of welding directly. The thicknesthickness of cold galvald galvanizing layer is 5-15um, can keep the product product out of rust for more than 2 years. But ho. But hot gat hot galvanize technology, the bestthe best of all in this field, iron art decoration products are put into about 455 degrees Zinc bath with Zinc rare earth alearth alloy and billet aluminumaluminum,luminum, is used by our Shou Jee iron art decoration corporation. The thickness of the hot galvanize laynize laynize laynize layer is above 65μμm, even come up come up tome up to 100&amp 100μm. The advantages of hot galvanize is that is that it has good cs good covering power, dense galvanize layer and without any organic maganic matter. The weather-resistant mechanism of Zinc incZinc includes mechanical protection and electrochemical protection: the surface of hot galvanize layer has ZnO, Zn(OH)2 , ZnCO3-, ZnCO3-2Zn(OH)2-H2O in atmospheric corrosion condition, which slow down th down the rusty of Zinc to a certain extent. Txtent. This protective layer called white rust can form a new layer while destroyed.&nb.  Weather-resistant power to base metallic iron of hot galvanize technology is much is much better than that an that of cold galvanizinlvanizing, and hot and hot and hot galvanizing can keep the products out of rust of rust of rust ov rust over 50 years.

Pt;p>Painting ainting technology: gloss of the painting divided into: light, mattht, matte, semi-matte, light divided invided intided into: touches, semiflat, dead luster. The brighter the paintings are, the more ageing-resistant they are. The drying functions are divided into surinto surface drying and hard drying with suitable moisture of 65 percent. Each kind of painting makes different drying time, to ensure the strength of adhesive force andorce and rce and tce and tce and to make to make it look the same he same as new, we control the drying time of following:

Nitryl lacquer basic painting surface drying time is 0.me 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 riczinc 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 finish coat surface drying time is 0.5 hour, hard dry time is 8hours

Alcohol acid gulf red finishd finish coinish 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
