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. Before placing an order with any factory, it is worth reviewing the guide to verifying certification claims on ChairManufacturer.net, which walks through what genuine test reports look like and the questions to ask a supplier. 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.
