Scaffold Tower Materials
In most parts of the world, aluminium or galvanized reinforced steel is used to construct scaffolding towers. In some Asian countries, bamboo is a frequently used and popular alternative. In the UK construction regulations dictate that either galvanized, or "black", steel or aluminium must be used.
Aluminium Scaffold Towers
When there is a choice between aluminium and steel scaffolds, aluminium is usually preferred because of its versatility. Aluminium scaffolding is much lighter than steel, which allows it to be constructed very quickly and easily and is frequently used for "do it yourself" projects. Despite its weight this material is very strong and robust. It can hold up to 600 lb (272 kg) and is thus very popular on construction sites.
Steel Scaffold Towers
Steel scaffold towers are heavier and when purchased, it is essential to verify that they were manufactured by skilled engineers from prime steel quality and not assembled in some back-shed or farmyard from scrap pieces of steel. While this may sound ridiculous, it does happen.
Galvanised Steel
The most resistant scaffold towers are made of hot dipped, galvanised steel which guarantees long term corrosion resistance. It will not rot, absorb moisture, split, splinter, swell, warp or burn. It is expensive to purchase yet its long term durability makes it a worthwhile investment as it will last you a lifetime. A further advantage of steel scaffold towers is that they are stiffer than aluminium ones over any given span. This reduces bounce and so provides a more stable platform.
Anti-Combustible Scaffolding
Certain work environments present great hazards. Regulations dictate that in such situations, only scaffold towers made of certain materials can be used. Boss Zone1 and Glass Fibre (GRP) are examples of two such materials. Boss Zone1 is non-conductive which makes it safe to use around electrical installations and maintenance work. It is particularly appropriate for use in electrical engineering applications and in the rail industry. As Boss Zone1 will not 'spark' it is save to use in areas where dust, vapour or other combustible material is present.
Corrosion Resistant Scaffolding
Glass Fibre is a tough, non-corrosive material which is resistant to corrosion caused by salt water, deterioration caused by caustic chemicals and damage arising from contact with gasoline, oils, lacquers and most solvents commonly found on industrial sites. Unlike aluminium it does not oxidise so keeps work surfaces clean and residue free. Glass fibre scaffolding towers are commonly used in a large number of various industrial locations such as oil refineries, off-shore platforms, power stations, chemical plants, gas industry, the aviation industry and many more.
Bamboo Scaffolding
Bamboo is an economical and environmentally friendly method of constructing a scaffold. It is a light, portable material which is easy to move from site to site. Weight and durability combined means that no machinery is needed to assemble or take down the scaffold. Recent research and development in construction has created a new and versatile scaffolding method by combining bamboo and metal in equal parts. This innovative solution combines the best elements of both materials; bamboo's durability and flexibility and steel's reinforced safety and strength.
