Detailed Product Description

furniture , iron furniture ,wrought iron furniture

Iron products have strict manufacture proture processes in designs, material sterial selection and manufacture craft

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

Material selection: we select high grade fine de fine steel (P less than 0.035 percent,S less th less thaless than 0.030  percen; percent)corcent)cold drawn steel which is in line with ISO9001 internatinternational standard.tandard. andard. Each steel material is strict selected with the surface neat ce neat and smooth, the separation angtion angle should be no less than 45 degrees between cross rib and steel bar surface, the surface should nshould not crack at the bend parts after bent 180 dnt 180 degrees flexural centre diameter, and steel bar surface should not crack , scar over or collapse.

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

Forging stock blanking, forging stock heating heating, roll forging for blank, stamp forging to certain shape, trimming cut, intermediate inspection, inspection of the size and sze 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 exterie exterior appearance and hce and hardness should bshould be ched 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, raight, smooth, and the arch sh 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 proportionoportion with the same model number should be the same and coincide completely. Any workpiece cut by plasma cutting or nong or not eas not easy to polish must be must be polished before gang welding. Accessory pieces must be forged or polished before bent in shape, then w, then welded with main iron art 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. 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 snd the size required by design are allowed to make a deviation of 1:1000 according to different products.

Hot galvanize technolotechnology: every piece can be welded all together should be welded before hot galvanize and it is not allowed to weld after hot galvanize without any special situation. For hot galvanize pranize 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 go out ogo 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 organic matter. The weather-resistant 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 condition, which slow down the rusty of Zinc to a certain extent. This protective layer called white rust can form a new layer while destroyed.  Weather-resistant power to base metallic iron 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 painting divided into: light, 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 ensure the strength of adhesive force 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 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 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
