Why wood and steel? Two materials that cover for each other

We’re not the first workshop to put solid wood on steel and we won’t be the last. Still, people keep asking why we do it. The answer is practical before it’s aesthetic: each material covers the other’s weak spot.

Wood moves, steel doesn’t

Solid wood swells and shrinks with the humidity in the air. Most of that movement happens across the grain: a 90 cm deep table top can shift by a few millimetres between a dry winter and a humid summer. Along the grain it barely changes at all.

Steel is the opposite. Indoors it keeps its size, doesn’t flex under load and doesn’t loosen over time.

So we use wood where we love it: on the surfaces your hands touch and your eyes rest on. And steel where something has to carry the load and stay put.

Slim legs, steady table

To keep a table with wooden legs from wobbling, the legs and rails need a certain bulk. Steel gives you the same stiffness from a much slimmer section.

• A 40×80 mm steel box section is noticeably slimmer than a wooden leg doing the same job.
• A welded frame can leave more room for knees than a frame built from joints and glue.
• On shelves, thin steel brackets let thick wooden boards look like they’re floating.

The result: the weight and warmth of solid wood stay up top, and everything underneath looks light and quiet.

Joining them: leave room to move

This is the part that matters most. Screw wood tight to steel and the wood will try to move anyway. Eventually something cracks or cups. So we build the connection to let the wood do its thing:

• Slotted holes: the screw holes in the steel frame are elongated across the grain. The screw is tight, but the top can still slide with the seasons.
• Threaded inserts: metal inserts go into the wood instead of screwing straight into it. The top can come off and go back on many times without stripping a thread.
• Fixed center, floating edges: the middle of the top is fixed and the outer fixings allow movement, so the top moves evenly both ways.
• Washers and felt: a small gap between steel and wood cuts down on friction and squeaks.

You’ll never see any of this. It’s exactly what keeps a table flat ten winters later.

Repairable, refinishable

Wood and steel can each be repaired on their own. For us that’s a big deal.

• The top will get scratched and marked over the years. It can be sanded and re-oiled.
• The steel frame can be recoated, re-blackened or switched to a different color.
• Because everything is bolted, top and base can be replaced independently. Legs come off for moving, so the table fits up narrow stairs.

With glued-up composite furniture that’s often impossible. When one part fails, the whole thing goes.

Finishing the steel

Bare steel rusts, so it always needs a finish. The main options we work with:

• Powder coat: oven-cured, electrostatically applied. The toughest option, in matte black or colors like our signal red.
• Blackening: a chemical treatment sealed with wax. You see the steel’s own texture and every piece is a little different. It asks for a bit more attention.
• Brushed and lacquered: raw steel brushed in one direction under a clear protective coat.

The materials page has the pros and cons of each.

The honest downsides

Like any material choice, this pairing has trade-offs you should know about.

• Weight. A solid top on a steel frame isn’t light. A large dining table like Beam is a two-person lift.
• Floors. Steel feet can scratch wooden floors. We fit felt or protective glides under every foot; replace them when they wear down.
• Cold to the touch. Steel feels cold, especially in winter. That’s why the places your hands rest the most are wood.
• Chips. Powder coat is tough but not invincible. A kick or a vacuum cleaner can leave small marks. Ask us for touch-up paint.

In short

Wood brings warmth, texture and the way it ages. Steel brings slimness, strength and stability. Joined properly, a table or a shelf looks good today and can still be repaired years from now. That’s what we’re after, whether it’s the Sled desk or the Beam dining table.
