High-Load Anchor

High-load anchors are a special type of fastener designed to withstand intensive mechanical impact of various kinds: wind, impact, seismic, and others. Such fasteners are used in the installation of critical structures: bridges, tunnels, floor beams, suspended elevators, and are also used in general construction work.

Anchors of this type are selected by length and diameter depending on the expected loads, and the fastener ensures reliable fixation of structures in the base material.

Design features

High-load anchors are made from carbon steel with a property class of 8.8 or higher. They are suitable for installation in the compression and tension zones of concrete, as well as in natural stone and other high-density materials. These products have several important features:

• Anti-corrosion zinc coating with a thickness of at least 5 μm. The protective zinc layer is applied by galvanizing, preventing the negative effects of corrosion and loss of fastener strength.
• A nylon ring. It is designed to seal the expansion zone and protect it from external effects. It also helps absorb impact and dynamic loads on the fastener.
• Controlled expansion of the anchor as the bolt is driven into the expansion zone. This ensures the strongest possible fixation, making the connection durable and long-lasting.
• High fire resistance corresponding to classes F30–F120. This provides the ability to withstand fire for an extended period in the event of a fire.
• Indoor use. Such anchors are designed for installation in various indoor spaces.

Anchors of this type are designed to create a high-strength connection. The bolt is screwed into the sleeve, causing it to expand and become firmly fixed in the material, with retention provided by friction. Such a connection is resistant to pull-out even under a sudden application of significant force. Anchors can withstand considerable mechanical loads over a long period of time.

Applications of this specialized fastener

This type of fastener is used to reinforce heavy structures that are constantly subjected to significant loads. These include support beams, structural elements of bridges and tunnels, elevator equipment, heavy gates, and more. Anchors of this type can also be used for installing gates, heavy door assemblies and fencing; in residential applications they are used to create connections with maximum reliability.

Such products are suitable for use in the installation of fire suppression systems. Thanks to their high fire resistance, the fasteners retain their original properties for a long time under intense heat.
