![]() ![]() Spring toggles consist of a screw and a set of metal wings which are equipped with springs. These anchors are mainly used for ceiling installations. The use of self-drilling plugs is generally reserved for lighter loads of 20 kg or less. When the screw is tightened, the outer thread separates slightly from the screw for a more secure hold. The fixing is held securely to the base material via the external fixing thread. Also known as self-tapping plugs, these fixings are usually screwed directly into the wall. Self-drilling plugs are screwed into soft, hollow materials (such as plasterboard) with or without a pilot hole. Be sure to check the manufacturer's specifications before purchase. The amount of weight a plug is able to withstand depends on the model, the base material and the number of plugs used. These plugs can support weights of 5 to 80 kg. When screwed into a surface, the fins are contorted before being pressed back against the base material in a tight knot to secure the fixing. Used exclusively for mounting light objects in hollow materials, these plastic wall plugs feature several nylon fins. The following are examples of hollow materials: Alternatively, book an appointment with an expert.Hollow materials are basically any material that is not solid all the way through.

Lightweight concrete blocks can be essential to the structural integrity of a project therefore, it’s extremely important to choose the correct one. For your other projects, we have a comprehensive range of concrete blocks available, including coursing blocks and aerated concrete blocks. If you're looking for lightweight concrete blocks, we work closely with leading manufacturers such as Plasmor, Forterra, and Cemex to provide a wide range of high-quality lightweight blocks, with our range of blocks coming in various dimensions, such as 440x100x215mm, 300x275x140mm, and 300x250x140mm to ensure that you can find the correct size and strength of product for your project. The density of the aggregate used is generally proportional to the strength of the block, for example, super-lightweight aggregates like expanded clay and pumice used for their excellent thermal performance, feature a relatively low compressive strength. Lightweight concrete blocks are manufactured from cement, mixed with one of a variety of natural or man-made expanded aggregates such as granulated or foamed blast-furnace slag, expanded clay or shale, furnace bottom ash (FBA), pulverised fuel ash (PFA), or the less common pumice (that is a volcanic material). The lightweight block enables time and material cost savings through easier handling than larger units or a different block type with the same dimensions. The main advantage of lightweight concrete blocks over dense aggregate blocks is a combination of higher insulating properties and a lighter block unit weight. Lightweight concrete blocks are used in both internal and external walls where loading is slightly more restricted, or as infill blocks in beam and block flooring. Lightweight blocks are produced in greater volume but are less strong than dense concrete blocks. Lightweight concrete blocks can be used in external applications as well as a versatile range of internal applications. ![]() Lightweight blocks are also manufactured with lightweight aggregates for a lighter more manageable concrete block. ![]() Lightweight concrete blocks are high-level performance in load-bearing and other structural applications. Lightweight concrete blocks are ideal for commercial and leisure developments, providing an even surface for paint and other finishes, with excellent resistance to air permeability. ![]()
