H-frame dining table base, cast iron and varnished steel Ø 42 mm
The H-frame in heavy pipe, for a dining table that stays put
With its 1 inch 1/4 black steel pipes (42 mm outside diameter) and its 100 mm floor flanges drilled with four holes, this H-frame base is designed for heavy tabletops and long spans: up to 136 × 71 cm, for a base weight of 16.8 to 21.2 kg. A solid worktop, an old door or a 4 cm oak slab all find a base built to their scale.
Malleable cast iron, black steel, screwed assembly
Six 1 inch 1/4 cast iron tees form the skeleton: two at the centre, four at the top of the legs. The black steel pipes screw into the threads, with no welding. At the top, a four-hole flange; at the bottom, a coupling with a black plastic insert. Built by hand in Annecy, entirely demountable.
Choosing your size
Size corresponds to the footprint on the floor. Allow 8 to 15 cm of tabletop overhang on each side: a 136 × 71 cm base takes a top of about 155 × 90 cm. Over long spans it is the thickness of the tabletop that becomes the limiting factor (see the dimensions table).
The height is fixed: 74 cm for the base alone. Add the thickness of your tabletop to get the final height — 74 + 2 cm = 76 cm, 74 + 3 cm = 77 cm. A dining table usually sits between 74 and 78 cm: a 2 to 3 cm top puts you right in that range. The underside of the top stays clear at 74 cm from the floor, which is 27 to 30 cm above a standard chair seat.
Tabletop thickness depends on the span between the legs. Up to the 106 × 61 cm size, 18 mm plywood is enough; from 116 × 61 cm upwards, allow 27 mm solid wood or the equivalent. These figures correspond to a deflection below 1/300 of the span under a 100 kg/m² load — the dimensions table gives the detail for every size.
Key features
Available in 9 versions, to be chosen above: footprint from 56 × 41 cm to 136 × 71 cm, base height 74 cm.
| Pipes | black steel 1"1/4 (33 × 42), giving an outside diameter of 42 mm — see the table of steel pipe diameters |
|---|---|
| Materials | malleable cast iron fittings, black steel pipes (black or galvanised steel?) |
| Finish | clear varnish applied to the cast iron and the steel alike, leaving the raw metal visible |
| Colour | Grey / anthracite grey depending on the light |
| Tabletop | not included — the Ø 100 mm flanges are drilled with 4 holes to screw on the tabletop of your choice, wood or glass (choosing a floor flange) |
| Flange spacing (centre-to-centre) | approximately the dimension minus 10 cm, in length as well as in depth |
| Floor protection | black plastic inserts under each leg |
| Assembly | delivered part-assembled — a few fittings to screw together on arrival (how to screw threaded fittings together), then fix your tabletop to the flanges |
| Weight | 16.8 to 21.2 kg depending on the version (table below) |
The same base, other pipe diameters
This H-frame base comes in three pipe diameters: Ø 27 mm, Ø 34 mm and Ø 42 mm (this page). The thicker the pipe, the heavier, steadier and bolder the base; the thinner it is, the more discreet the silhouette. The same frame is also offered at coffee-table height (34, 44 or 54 cm).
Details and features
The metal is protected by a clear varnish that preserves its raw look: care for it with a soft, dry cloth, without water or abrasive cleaners. For indoor use only.
The photos showing a tabletop are for illustration only: the tabletop is not included.
The materials may show slight differences in appearance compared to the photographs. These imperfections, which make each piece unique, are part of the raw, authentic and unmistakably industrial character of every item sold by Home Invasion.
Assembled to order in Annecy, France.
Detailed dimensions
The letters refer to the drawings below. All dimensions in centimetres; dimension A is measured from the outer edge of one flange to the opposite flange. Centre distances (B, D) are measured between flange centres — useful for drilling the top.
Tolerance: these are nominal dimensions. How far each fitting is tightened, together with casting tolerances, gives about ± 5 mm of variation on each dimension. Measure the base once assembled before drilling your tabletop or having it cut.

For cutting the tabletop and fixing it to the flanges, our tutorial building an industrial-style desk from plumbing pipe takes you through it step by step.
Would you rather build it yourself?
Nothing here is welded: the base is a set of fittings screwed into one another, which you can redo, extend or take apart. Every part is sold individually in our catalogue, and the pipe lengths are standard references, not special cuts.
