Product Description

The Fixed-Height Single Student Desk and Chair Classroom Set, model SDC-F6040-YR, is an unbranded steel-wood public education furniture set designed for consistent, high-frequency use across learning environments. Visually, the set features warm yellow wear-resistant melamine panel surfaces accented by bold 2mm red PVC impact-resistant edge trim on all exposed panel edges, paired with a matte light gray powder-coated steel frame, delivering a bright, orderly aesthetic suited to structured learning spaces. All panel corners are rounded and finished with PVC trim to eliminate sharp impact points, and black anti-slip rubber foot caps cap every leg end for a polished, floor-safe finish.
Constructed for long-term durability, the set uses E1 grade melamine laminated MDF for all work surfaces: the 30mm thick desk worktop offers a flat, stable writing plane, while 18mm thick panels form the 380mm square seat and matching backrest. The structural frame uses 1.5mm wall thickness oval steel tube, reinforced with 1.2mm wall thickness round steel cross-bracing welded to leg assemblies, with all steel components treated via pickling, phosphating, and electrostatic powder coating to deliver 240 hours of neutral salt spray corrosion resistance, H-grade surface pencil hardness, and grade 2 coating adhesion. A 0.8mm cold-rolled steel undershelf matches the frame finish, and zinc-plated steel hex bolts with lock nuts enable secure knock-down assembly; rubber foot caps prevent floor scratching and unwanted movement during use. The full set carries a 5-year structural warranty, with a 15kg net weight, 100kg desk worktop static load capacity, and replaceable panels to extend service life.
Practical functionality is tailored to education settings: the fixed, non-adjustable frame supports consistent ergonomic positioning for recommended users aged 16, with a 460mm seat height, 760mm desk height, and 580mm seated knee clearance paired with an open front central knee bay for unobstructed entry and exit. A full-width fixed metal undershelf provides open storage for books, stationery, and school bags, while the armless cantilever chair design allows stacking up to 5 units high to simplify space reconfiguration. The set arrives in 2 cartons per unit, with pre-drilled components enabling 40 minutes of on-site assembly per set; 135 sets fit in a 20GP container at 85% space utilization for efficient bulk shipping.
This set is suited for middle school general classrooms, institutional training centers, tutorial schools, individual dormitory study spaces, after-school program facilities, standardized exam halls, and short- or long-term education furniture rental fleets, as its scratch-resistant laminate surfaces and heavy-duty frame withstand repeated daily use. Procurement teams should note the fixed, non-adjustable height is purpose-built for the specified user demographic, plan for on-site knock-down assembly labor, account for 2 cartons per set with a 23kg packaged gross weight per unit, and leverage the stackable chair design to reduce storage footprint during non-use periods.
