Wood, metal or PP: how we steer a restaurant dining-chair order

The first thing a restaurant buyer wants from us is a material recommendation, and the honest first answer is a question back: how hard is the room, and how often will a chair get dragged, stacked and wiped down a day? "Best" is not a property of wood, metal or polypropylene. It is a property of the match between the material and the abuse. Here is how we actually decide on a dining chair order, told through how each one breaks.

Metal: the durability-to-cost benchmark

For most restaurant segments, a steel-frame chair gives the best durability for the money, and the number that matters is wall gauge. The commercial benchmark people quote is 16-gauge steel tube — lower gauge means thicker wall and a frame that survives being kicked across a tile floor for years. The trap is that gauge is invisible on a finished, painted chair. A 18- or 20-gauge tube looks identical in a photo and weighs less in the box, which is exactly why a price-cut supplier reaches for it. We state tube wall thickness in mm on the quote rather than letting "steel frame" do the talking, because the difference shows up as a bent leg in month eight, not on the showroom floor.

Wood: warm, repairable, and slower to abuse

Solid hardwood — beech, oak, ash — has a real place, and not only for looks. A wood joint can be re-glued; a cracked weld usually cannot. The weakness is the surface: hardwood scratches and water-marks, and in a high-turn bistro the seat edges scuff where chairs knock the table base. Wood also moves with humidity, so a chair built for a dry European dining room can loosen at the joints in a humid coastal venue. We build wood for slower-turn, design-led rooms where the look earns its keep, and we are blunt about the maintenance it asks for.

Polypropylene: light, cheap to ship, honest about its limits

PP shell chairs are light, stack well, wipe clean and survive rain on a covered terrace. They are the workhorse of fast-casual and cafe seating. The limit is plain: a soft or under-filled PP shell flexes, and a flexing shell eventually cracks at the leg junction under a heavier guest. Good PP uses virgin resin with UV stabiliser and enough wall thickness; the cheap version is recycled regrind that goes brittle in sunlight. We will tell you which one a quote is, because you cannot see it.

The trade-off we put on the table

Here is the line we give operators almost verbatim. For a high-turn casual dining room or a food court, we push you to a properly gauged steel frame — it costs a little more per chair than thin tube or budget PP, and it is the one that does not generate a replacement order in eighteen months. For a covered terrace or a grab-and-go cafe, PP earns its place on weight and price. For a destination restaurant where the chair is part of the design, wood, with eyes open about scuffing. Mixing is fine, and common: steel base lines in the busy zones, a wood or upholstered hero chair where guests linger.

We build dining frames to EN non-domestic seating methods (EN 16139), and testing to a named level can be arranged per order — we do not pre-print a certificate that may not match your final build. Send us your room type, daily covers and target landed price, and we will recommend a material and quote the gauge or wall thickness in writing.
