Metal grating versus fibreglass or grp


Despite the tempting initial price of metal gratings (or traditional gratings) which are often chosen in a hurry on the sole basis of their apparent economic benefits, in the long term they involve costs which have a negative effect on the investment:
•Safety-related costs:
Due to the poor slip-resistance of metal gratings when water, grease, oil, ice etc. are present.
Disadvantages: Accidents at work, risk of injury to personnel and consequent reduction in company profitability.
•Maintenance costs and low chemical resistance of the material:
Rapid corrosion even in conditions of minimal chemical aggression, leading to a need for frequent replacement
•Manpower costs for installation and transport:
Greater physical effort and the use of lifting equipment for the installation and movement of metal gratings due to their weight which is 3 times more than that of fibreglass gratings; this also has a negative impact on transport costs
•Cost of shaping, cutting and drilling.

POWERGRATE® fibreglass gratings, by contrast, prove to be an excellent investment because they are characterised by:
•Long-lasting corrosion resistance even in harsh conditions (immersion, or continuous contact) with very aggressive products (e.g. sulphuric or hydrochloric acid)
•Guarantee of markedly greater safety, even in extreme conditions (grease, oil, or waxes) ensured by the special permanent anti-slip surface (DIN standard 51130 class R13-V10)
•Lightweight, simple to install and remove, easy to move
•Zero maintenance, easy to cut and shape
•Characteristics of internal resilience which alleviate the backache typical of personnel who spend a long time crossing or standing on gratings (ergonomics) resulting in increased profitability
•Thermal and non-magnetic insulation characteristics: Excellent thermal and electrical insulation with no need for earthing (antistatic and conductive versions available on request)
•Self-extinguishing properties of the resins and low toxicity of halogen-free fumes: Maximum safety in all environments and protection of personnel in the event of fire.
