The first point: the raw materials of the pillars: Φ120mm and Φ114mm national standard galvanized pipes are selected, with a thickness of 2.5mm. After all processing, they are derusted and sandblasted by special technology.

Outdoor polyester resin (polyesr/TGIC system) resin powder coating baking varnish, high temperature curing, smooth surface, anti-ultraviolet, bright color, not easy to fall.

The second point: channel raw materials: high-strength cold-rolled steel plates with thickness of 2.0 and 2.5 are punched. After special technical treatment, the appearance is wave-like, safe and beautiful, and has good anti-skid properties.

Surface treatment: A. Anti-slip plastic coating B. Resin paint.

The third point: steel pipe fittings raw materials: outer diameter 28/32/38/48/60/thickness 2.5m welded pipe surface treatment: outdoor polyester system (polyesr/TGIC system) resin powder coating and baking paint.

Fourth point: plastic parts raw materials: imported food-grade non-ferrous plastic, slide thickness: 10mm, other types thickness: 5mm, low density polyethylene with anti-ultraviolet stabilizer and static avoider, high strength, lubricated appearance, safety and environmental protection, weather resistance Good, not easy to fade. Surface treatment: Die-cast surface.

Sixth point: hardware parts raw materials: stainless steel dome head, T-shaped flat head screws Surface treatment: mechanical polishing.

Seventh point: raw materials for children's amusement park equipment fasteners: the fasteners are connected by stainless steel screws, and the contact points between the buckle and the column are added with rubber pads and machine-meter fastening screws to enhance its safety.
