Anchor Fasteners
What are Anchors?
Anchors are fastenersused to connect structural and non-structural elements to concrete or masonry. Anchors work by embedding into a base material and expanding, bonding, or threading to achieve holding strength. Used extensively in infrastructure, heavy equipment, and building installations, anchors come in different types like wedge, sleeve, chemical, and drop-in.
Asiad Steel Industries serves as a leading manufacturer, supplier, and exporter of durable anchor fasteners, engineered for secure fixation in concrete and masonry for construction and industrial projects.
