— HZ-ST-630

Z-frame student chair
moulded seat & back

The HZ-ST-630 is a robust student chair with a separate moulded seat and a contoured back panel mounted on a continuous-tube Z-frame. The single bent-tube frame gives the chair a slight cantilever spring and a stable wide footprint, while the two-part shell keeps the seat and back individually replaceable over a long service life. Powder-coated in any frame colour — bright pink shown — with black ABS foot caps that protect finished floors.

— Engineering highlights

Simple, sturdy, serviceable.

— 01

Two-part replaceable shell

The seat and back are separate moulded panels bolted to the frame, so a single damaged part can be swapped on site instead of scrapping the whole chair — lower lifetime cost for large estates.

— 02

Continuous-tube Z-frame

One bent steel tube forms the legs and base, giving a wide, stable footprint with a slight cantilever spring. Fewer welds means fewer failure points over years of daily use.

— 03

Any frame colour

The frame takes any powder-coat colour — the bright pink shown, school-brand tones, or year-group colour coding — with a hard-wearing finish that resists chips and scuffs.

— 04

7-stage anti-rust frame

The steel frame goes through degreasing, phosphating, electrostatic powder-coating, and high-temperature curing, holding its finish in coastal and tropical climates. 5-year structural warranty.
