Product Description
[Main Technical Parameters]:
◆ Directly buried type: the main upright posts are made of standard rectangular galvanized steel tubing measuring 120 mm × 80 mm with a wall thickness of 3 mm, and both sides of the posts are equipped with…
Use plug‑in aluminum alloy profiles combined with wood‑plastic composite profiles; the overall external dimensions of the uprights shall be no less than 120 mm × 120 mm.
◆ The handrail bends are fabricated from national-standard steel tubing with a diameter of 42 mm and a wall thickness of 2.5 mm.
◆ The main frame’s support tubes are made of 40×80×2 mm square tubing to prevent users from getting caught and injured.
◆ The equipment panel is fabricated from 1.8 mm-thick cold-rolled steel sheet, with both sides fully enclosed by 1.8 mm-thick cold-rolled steel to prevent injury from clamps.
◆ The equipment nameplate is made entirely of stainless steel, secured with rivets, and its edges are tightly fitted against the upright posts to prevent snagging, scratching, and other potential damage.
◆ The equipment has undergone relevant static load and strength load tests in accordance with the GB 19272-2024 standard and complies with the standard’s requirements.
◆ The entire machine has no snagging, crushing points, shearing points, or pinching hazards; all apertures and gaps comply with GB 19272-2024. Standard;
◆ The equipment features a one‑stop exercise station, allowing a single user to operate it simultaneously.
◆ The embedding depth of the equipment upright shall be no less than 400 mm, and the underground dimensions shall be no less than 400 × 400 × 500 mm.
◆ The components are cut using a laser cutting machine, ensuring high efficiency and precise positioning. The pipe-bending process employs a CNC pipe bender, with angles… Accurate dimensions and aesthetically pleasing appearance; prior to welding, the components undergo degreasing to ensure that no oil or grease remains on the workpiece surface. Welding… Using a CO₂ shielded welding machine with a mixed gas, the welds exhibit an attractive appearance and straight bead profiles, eliminating the need for grinding. It is also equipped with a dust collection and treatment system to purify the workshop air, ensuring workers’ health. Surface treatment is carried out using blasting. Round‑edge finishing ensures thorough rust removal and enhances the adhesion of the plastic powder. The electrostatic spraying process employs a two‑coat application: first, an epoxy zinc‑rich primer is applied, The exterior surface is coated with an environmentally friendly, green electrostatic powder. Utilizing imported electrostatic spraying equipment, the coating delivers uniform powder distribution and strong adhesion. The finished surface exhibits excellent resistance to acids and alkalis, withstands humid‑heat conditions, resists aging, and maintains an attractive appearance—making it well suited for damp environments and areas prone to acid rain. The product’s coating formulation contains no toxic elements, and a cyclone‑type centrifugal powder recovery system ensures a recovery rate of up to 98.6%, reducing material waste and minimizing dust pollution while offering convenient operation and energy efficiency.
◆ The equipment is packaged in a double-layer system, effectively preventing impacts and scratches during transit, ensuring the equipment remains undamaged.
