Trestles are basically a framework that's made up of horizontal beams connected to two pairs of sloping legs that help stabilise the weight and distribute it evenly.

Bricklayers lay bricks, blocks and other types of building components in mortar to construct and repair walls, foundations, partitions, arches and other structures, such as chimney stacks.

Trestles are rigid frames that can support anything from tables to staging boards, typically made out of wood, metal, or plastic. Trestles can be fixed, foldable, or adjustable and are used by many professionals for a variety of reasons.

Safety measures during scaffolding dismantling Clear the platform of all materials and debris before dismantling the scaffolding. No materials to stack or leave on the structure temporarily ,but brought to the ground straight away. Never throw or drop scaffold member to the ground.

Trestle supports are used for work on a large area if little or no adjustment of height is required (e.g., for plastering the ceiling of a room). The trestles may be of special design or simply wooden sawhorses of the type used by carpenters.

Bricklayers and plasterers are responsible for the building of the inner and outer walls of a building as well as the finishing of these structures. Bricklayers construct and repair walls, partitions, steps, free standing piers, arches, fireplaces and other structures made of brick, concrete block or masonry materials.

Trestles come in wood, metal or plastic. They can be folding, fixed or adjustable and can support work surfaces or tables and desks. For builders and architects, at home or in the workshop, trestles have many uses.

Follow these steps to dismantle a trestle scaffold: Step 1: The first thing that you need to take care of is safety. Step 2: Start the process from the top of the scaffold. Step 3: If the guardrails and toe boards were mounted, remove them first. Step 4: Hand over the dismantled part to the person at a lower point.

In structural engineering, a trestle support (or simply trestle) is a structural element with rigid beams forming the equal sides of two parallel isosceles triangles, joined at their apices by a plank or beam. Sometimes additional rungs are stretched between the two beams.
