Indoor Retractable Bleachers With Rear-folding Seat YY-ZT-P
Seat material introduction: High-density polyethylene (HDPE) is used as the raw material, and hollow blow molding is integrally formed. This material has good waterproof and impact resistance, good mechanical strength and chemical stability, and good weather resistance (resistant Heat and cold resistance), the seat color uses professional coloring master batch, which can ensure the color lasting and beautiful, the seat color can be customized according to customer requirements, and personalized color schemes can be designed for different venue characteristics.
Seat installation beam: The beam material is made of 60*40*3 high-quality square steel. The tube cutting, shaping and drilling are all automatically performed by the fiber laser tube cutting machine, with high precision and excellent processing performance. The surface of the beam is electrostatically sprayed. The thickness of the powder is 60-80um measured according to the standard GB/T 1764 "Method for Measuring the Thickness of Paint Film". The surface of the coating is smooth, without blistering, pinholes, cracks, burrs and scratches.
Seat Folding Bracket: Using 3mm thick hot-rolled sheet as raw material, this hot-rolled sheet has good toughness and ductility. It is cut by laser, bent and welded to shape (high dimensional accuracy), and then polished after molding. , After sandblasting and rust removal, the surface is sprayed with powder (the thickness of powder spraying is required to be no less than 80μm), and the finished product has a simple and beautiful appearance.
Rear-mounted folding mechanism: The rear-mounted folding mechanism parts are cut by laser and formed by molds. The main material is Q235, which conforms to the GB50017-2003 "Steel Structure Design Specification". It adopts the folding mechanism independently developed by the company with patent specifications. Pneumatic turning, the process of turning and placing is smoother, less effort, self-locking in place, safe and reliable, and sensitive.
Soft bag: The seat can be equipped with a soft-covered seat surface, using high-grade fabrics, wear-resistant and fade-resistant, and feel more comfortable. The inner lining is made of high-density cold-foamed shaped cotton, which enhances the durability of the seat. The color of the seat can be changed. Customized according to customer needs.
