Scaffolding is a vital part of almost all projects of construction. It has been in use ever since the building of the first structures. Typically required to gain access to structures at height during construction, scaffolding can serve many objectives.
At times scaffolding is used to support workers and their tools; they are also used to support significant loads from building materials like concrete, stucco, bricks, and blocks.
Scaffolding is a temporary and sometimes moveable fabrication used by workers all through the construction industry. These platforms are usually constructed out of wooden planks and metal poles used to raise and support workers, materials, and machinery.
Materials for scaffolding
Scaffolding dealer offers the following choices of materials:
Planks are crucial for safe conditions on a scaffold for properly supporting workers and their tools. Commonly wood is made of pine or fir.
It is a corrosion-resistant, ductile and soft metal with properties that make it ideal for scaffolding applications. This scaffolding is lightweight, secure, stable, and needs minimal maintenance efforts.
Such scaffolding provides excellent durability and strength while maintaining elasticity that helps prevent cracking. Heavy loads can be supported by steel and are needed for tall structures, where the weight of scaffolding itself needs structural strength.
Types Of Scaffolding
- Single scaffolding
Also called a bricklayer’s scaffolding, it is placed 1.2 m away parallel to the wall. Standards are set around a distance of 2 to 2.5 m, while ledgers help to connect the standards at 1.2 and 1.5 m vertical levels.
- Double scaffolding
Also called Mason’s scaffolding, it is often used for stone masonry and is composed of two rows of scaffolding for extra strength. The first row is placed around 20 to 30 cm from the wall, while the second is 1m from that. Cross bracers and strong rakers offer extra strength.
- Cantilever scaffolding
Also called Needle scaffolding, it uses needles made of timber that is extended out of or cantilevered from holes in the walls of buildings. Such needles will support the complete scaffold structure. This scaffolding is used when the ground will not support a conventional scaffold, when a road or side block cannot be blocked or when maintenance or construction is needed at a great height.
- Suspended scaffolding
This scaffolding uses ropes or other rigging systems to suspend the scaffold platform from an overhead structure. Such a rigging system enables workers to raise or lower the platform as required to reach the desired work level, like in the case of a high-rise building.
- Trestle scaffolding
This scaffolding is a versatile system suitable for simple jobs and maintenance projects. The design of trestle scaffolding renders it easy to move and is mostly used by builders and painters when there is a need for a secure and flexible platform.
- Steel scaffolding
It is a highly durable system of scaffolding constructed with steel tubes combined with fittings for easy assembly and dismantling. It offers powerful strength, high fire resistance, and much durability; it is popularly used when a complete structure is under maintenance.
Sometimes called Modular scaffolding, this scaffolding consists mainly of horizontal and vertical pre-engineered components which connect together in a systematic fashion. It is the most popular kind of scaffolding all over the world. Some function well in highly loaded conditions, while others are suited to small, repeated scaffold structures.
In sum, these are the main kinds of scaffolding in the market.
