Stainless steel has a life expectancy of over 1000 years and is a highly durable material for external sign manufacture as it never corrodes and is extremely robust.
Oak is a “Class 2” hardwood with a life expectancy of 15 to 25 years. It requires regular maintenance to keep it in good condition and prolong its life. See our maintenance instructions for further details.
Recycled plastic requires no maintenance and has a life expectancy in excess of timber. It never rots and is impervious to insect infestation. We do not recommend this material for sites where vandalism may be a concern.
