Arches and lintels are both used to support the weight of a structure above an opening. However, arches require special centering and formwork for construction, while lintels are simpler and easier to construct. Lintels can be made from a variety of materials, including wood, stone, brick, reinforced brickwork, RCC, or rolled steel sections embedded in cement. Arches can span both small and large distances. Props supporting beams and arches over 20 feet can be removed after three weeks. Curved stairs are a decorative and fascinating part of construction, but they are also very difficult...

However, arches require special centering and formwork for construction, while lintels are simpler and easier to construct. Lintels can be made from a variety of materials, including wood, stone, brick, reinforced brickwork, RCC, or rolled steel sections embedded in cement. Arches can span both small and large distances. Props supporting beams and arches over 20 feet can be removed after three weeks. Curved stairs are a decorative and fascinating part of construction, but they are also very difficult to make. Formwork for concrete stairs is used to create the overall shape and size of the stairs. It also helps keep the shape in place until the concrete sets. Here are some tips for using formwork for concrete stairs: Basic principle: Treads should not be formed, but left open. Concrete mix: A good quality concrete mix with a standard slump should not pour out of the bottom in a flood. Smooth surface: The surface should be smooth, bright, and clean. Resistance: A 20mm stair tread provides resistance against chipping with no patch-ups required. Formwork should stay in place for at least a week. Forms and props can be removed for slabs spanning up to 4.5 m(either direction) after 7 days.
