This comprehensive range of plain, crested and concrete finial ridges and finials are manufactured in glass reinforced cement to the highest standards by Roofing Products (UK) Limited; a member of the Harris Group.

The range which is hand finished is produced at our modern factory in Leigh, Lancashire. The ridges are manufactured to resemble either natural clay or fibre cement ridge and can be used on various ridge or hip detail.

The ridges and finials are shown below and are available in Terracotta, Blue/Black, Smooth Brown, Smooth Grey, Blue/Grey* and Brown/Black* (where * denotes internally socketed Dry Fix Ridge only).

Physical and Chemical Characteristics

These products are cement based materials reinforced with glass fibres. They contain portland cement, sand, glass fibres and pigment. The surface is coated with water based paint. This results in a very durable and uniform product.

Storage

GRC Ridges are stacked on pallets and shrink wrapped. The weight of these packs vary according to contents. The maximum pack weight is 700kg. Care must be taken when opening the shrink wrapping to avoid the ridges falling out. Pallets can be stacked on dry level ground but no more than 3 high. Packs lifted above storey height should be contained by a safety cage and personnel should stand well clear of movements.
