Steel Plate Flag Bases | 4 kg to 12 kg Square Plate Bases

A steel plate base is the most stable thing you can put a flagpole on, and the least forgiving. It holds by mass on flat, hard ground — and it is the only family here that can damage the surface it stands on.

The range covers two shapes: a large square plate built for a single tall pole, and a flat plate made in four weight grades for telescopic and banner flag poles.

Steel plate flag bases: square plate bases in two sizes and flat steel plate bases in four weight grades

The models

Square plate bases — iron, powder-coated. The heavier duty option, built for a single tall pole:

Model Weight Plate size
Square plate base — small 6.3 kg 39 × 39 × 0.5 cm
Square plate base — large 12 kg 50 × 50 × 0.8 cm

Both can be fitted with a 90° adapter or a separate rotator, so the same plate serves a vertical pole, an angled pole, or a pole that must swing to the wind.

Flat steel plates — iron, powder-coated, in four weight grades. The plate is identical across both versions; what changes is the fitting that holds the pole:

Version Pole fitting Effect
Flat steel plate — with rotator A rotating rotator The pole swings to face the wind. The right choice outdoors, for feather and banner flags
Flat steel plate — with fixed post A single fixed post The pole is held rigid in one orientation. For indoor displays and camera-facing positions
Weight grade Plate size Packed
4 kg 30 × 30 × 0.6 cm 32 × 32 × 3.5 cm
6 kg 35 × 35 × 0.6 cm 37 × 37 × 5 cm
8 kg 37 × 37 × 0.7 cm 39 × 39 × 4 cm
12 kg 48 × 48 × 0.7 cm 50 × 50 × 2 cm

Why plate size beats plate weight

Stability is a lever problem, not a mass problem. A plate holds a pole up because its footprint reaches past the point where the flag’s load pushes down. A small heavy plate and a large lighter plate can weigh the same and behave completely differently.

That is why the grades step up in both weight and diameter: 30 cm at 4 kg, 35 cm at 6 kg, 37 cm at 8 kg, 48 cm at 12 kg. If you are choosing between two grades, choose the one with the larger plate.

Where steel plates work, and where they do not

Ground / setting Verdict
Flat paved forecourt, indoor hall Best choice — maximum stability, no fixings
Polished indoor floors Use a base with rubber feet, or a water base — a bare plate scratches
Grass, soil, sand Wrong choice — it sinks and leans
Roof or exposed site Add the flag’s wind load to the specification before choosing the grade
Left outdoors in a public place Plates are heavy, but theft still happens — consider a spiked or bolted alternative

Ordering

No minimum order. Plates are dense and compact, so they are the cheapest base family to freight by sea — the packed sizes above let you calculate the container before ordering.
