50cm Stainless Steel Bird Spikes | 20-Pair OEM Strip

50 cm strip / 20 pairs / 40 pins / 304 base and spikes / unassembled

These 50cm stainless steel bird spikes use an open 20-pair layout with 40 pins. Both the mounting base and the pins are specified as 304 stainless steel, and each strip is supplied unassembled for wholesale, OEM and project orders.

Open 20-pair layout for specified projects

This 50cm strip has 20 pin pairs, giving a total of 40 pins. It is a distinct format from our 30-pair 50cm strip, which carries 60 pins. Choose the pin count required by the approved sample, site specification or retail programme rather than assuming that a different density is automatically better.

The crossed-pin pattern creates a physical barrier over narrow landing edges. Final performance depends on complete coverage, fixing strength, bird pressure and whether nearby ledges offer an easier place to land.

Where the 50cm strip fits

Plan fixing and full coverage

1. Measure the landing surface. Record length, depth, corners and any returns or adjoining ledges.
2. Check the substrate. Confirm a suitable mechanical fixing for masonry, timber, metal or the actual mounting surface.
3. Dry-fit the strips. Mark fixing positions, cut where necessary and remove gaps that could still support a bird.
4. Protect services and access. Keep drains, vents, window movement, lighting and inspection routes clear.
5. Recheck after severe weather. Inspect loosened fixings, debris and uncovered footholds.

Selection note: 304 stainless steel is a general-purpose grade. Coastal salt exposure, high-chloride environments or chemical processes should be reviewed for grade 316 or another suitable specification.

50cm stainless steel bird spike specifications

The supplier data lists a 53.2 × 11.2 × 5 cm inner box and a 55 × 37 × 22.5 cm outer box with 12 sets. Confirm final carton quantity, product assembly state and export packing before bulk production.

Compare the 40-pin and 60-pin formats

For the denser format, compare our 50cm full stainless steel bird spikes with 30 pairs / 60 pins. For a transparent PC base and another pin arrangement, see the 50cm 3+2-pin stainless steel strip.

The correct comparison is the approved base material, total pin count, strip length, fixing method and delivered packing. A higher pin count does not replace measuring the full landing area.

Unassembled OEM supply

Unassembled strips can suit buyers who assemble or pack locally, need a particular freight and labour balance, or source a standard component for private-label production. Compare landed cost, assembly instructions, retail presentation, accessories and carton utilisation before selecting this format.
