In order to facilitate transportation, the balcony guardrail is generally assembled. The crossbars are in accordance with the specifications and spacing requirements of the vertical rods. The imported equipment is standard punched for easy insertion and assembly of the vertical rods. The stainless steel anti-theft spring is fixed and the waterproof ring is sealed. The connection of the column is generally a three-pack card and a special anti-theft bolt.
The zinc steel guardrail in the new guardrail is made of hot-dip galvanized steel pipe as its raw material. Its strength and characteristics are far superior to ordinary low-carbon steel wire and black welded pipe. It is not only better than ordinary guardrail. And corrosion resistance, under the impact of strength, not easy to deform, broken, the general zinc steel guardrail uses three crossbars, the vertical bar spacing is not more than 12 cm, the column can be arbitrarily matched, but must also consider its crossbar and vertical bar Coordination.
There are two most commonly used:
The first type is standard: Crossbar: 32*32*1.2mm Vertical bar: 16*16*1.0mm Column: 50*50*1.5mm
The second type is enhanced: Crossbar: 40*40*1.2mm Vertical bar: 19*19*1.0mm Column: 60*60*1.5mm
The thickness can be adjusted according to customer requirements, the height is generally not more than 2 meters, 1.2 meters and 1.5 meters are used more.
The process of static spray of balcony guardrail:
Purpose: To remove the oil, dust and rust on the surface of the workpiece, and to form a "phosphating layer" on the surface of the workpiece that is corrosion-resistant and can increase the adhesion of the spray coating.
Process steps: degreasing, descaling, phosphating, passivation. After pre-treatment, the workpiece not only has no oil, rust and dust on the surface, but also produces a uniform and rough gray phosphating film which is not easy to rust on the silver-white shiny surface, which can prevent rust and increase the spray coating. Adhesion.
2. Electrostatic spraying:
Purpose: Spray the powder coating evenly onto the surface of the workpiece. Special workpieces (including locations where electrostatic shielding is easy to occur) should be sprayed with a high-performance electrostatic sprayer.
Process steps: Using the principle of electrostatic adsorption, a layer of powder coating is evenly sprayed on the surface of the workpiece; the dropped powder is recovered by a recovery system and can be reused after being sieved.
3, high temperature curing: fryer
Purpose: To heat the powder coating on the surface of the workpiece to the specified temperature and keep it for the corresponding time to melt, level and solidify, so as to get the surface effect of the workpiece we want.
Process steps: Push the sprayed workpiece into the curing oven, heat it to a predetermined temperature (typically 185 degrees), and keep it for the corresponding time (15 minutes);
