SPIKES SPECIFICATION
General
Can have all plastic spikes, all metal, or plastic base with metal wires. Latter generally preferred as all plastic can suffer problems with effectiveness and visibility; and all metal can be more difficult to glue. Specification of wires and bases can vary significantly - select according to requirement
Wires
Diameter - thicker wires are more difficult for birds to push through
Tensile Strength - spring grade steel is harder to push through
Security - insert moulding rather than just pushing in to plastic base is stronger
Material - 302 grade stainless steel adequate for majority of installations, 316 grade preserves appearance in heavily polluted or marine installations
Angle - wires leaning outwards at circa 45° are more difficult for birds to push through than vertical wires, so are better for heavier pressure
Height - 95mm min for pigeons, 140mm min for gulls
Spacing - 50mm max for pigeons, 40mm better for heavy pressure
Tips - need to be blunt to conform to UK legislation
Wires insert moulded into base
Bases
Material - strength, UV protection, bond-ability
Width - affects stability: wider bases for heavy pressure
Length - 1/3 metre strips - easy to calculate quantities
Height - insert moulding means lower profile/more discreet
Glue Guide - groove in base for easy glue application
Holes - for rivets of glue or for screws

- UV protected polycarbonate
- Glue Guide for easy glue application
- 33.3cm long
Wires
- Stainless steel 302 (also marine grade option)
- 1.42mm diameter
- High tensile >1500N/mm2
- Insert moulded into base so wires held tight and base compact with low profile
Packing
- Low profile strips fit closely together in stacks of 5m (15 strips)
- Low profile means 50m cartons are small. Allows easyhandling and minimal storage space
