---|---|---|---|---|
Corrosion Resistance |
Excellent Corrosion ResistanceCan be designed to suit most chemical environments. |
Low Corrosion ResistanceSubject to oxidation and corrosion.Requires painting or galvanizing. |
Low Corrosion ResistanceSubject to galvanic corrosion. Requires anodizing or other coatings |
Low Corrosion ResistanceCan warp, rot and decay from exposure to moisture, water and chemicals. Requires coatings or preservatives. |
Weight |
Lightweight(Up to 80% lighter than steel & approx. 30% the weight of aluminium) |
Extremely HeavyRequires heavy lifting gear to manoeuvre. |
Lightweight(about 1/3 that of copper or steel) |
Dependent on size |
Slip Resistance |
Extremely High Slip ResistanceRelinea’s integral grit finish offers the highest degree of slip resistance ever measured for a walking surface, even in wet or oily conditions. |
Little or No Slip ResistanceA major health & safety risk for companies. |

Strength |
High Strength-to-Weight RatioStronger than steel on a kg-for-kg basis. |
High StrengthHeavy in weight to achieve its high strength properties. |
Low Strength |
Dependent on SizeTo achieve reasonable strength properties product sizes have to be extremely large. |
Impact Resistance |
High Impact ResistanceWill not permanently deform under impact. |
Medium to Low Impact ResistanceCan permanently deform under impact. |
Low Impact ResistanceEasily deforms under impact. |
Medium to Low Impact ResistanceCan permanently deform under impact. |
Fabrication |
Easily Field FabricatedCan be easily field fabricated using simple carpenter tools with carbon or diamond tip blades. Lightweight for easier erection and installation. |
Fabrication more ComplexOften requires welding and cutting torches. Heavier material requires special handling equipment to erect and install. |
Fabrication more ComplexWelding, brazing, soldering or mechanical joining required. |
Easily FabricatedFabricated using tools such as jigsaws and circular saws. |
Maintenance |
Maintenance FreeGRP has a design life of 50 yrs. |
Constant Maintenance RequiredDue to rust, damage, or re-painting. High cost implications. |

Cost |
Long Term Cost SavingsLower installation and maintenance costs in industrial applications = very low lifecycle costs. |
Low Cost, High MaintenanceLower initial material cost, however costly to maintain. High lifecycle costs. |

Ergonomic |
Good Ergonomic PropertiesThe innate elasticity of GRP provides comfort to workers as it has a slight ‘give’ underfoot. |
No Ergonomic PropertiesSteel does not provide comfort underfoot. Can lead to back ache for workers who are on-foot for long periods of time. |
