Product Type: Extended Explosion-Type Expansion Structure
Product Description
Product Overview
This product is an extended ceiling expansion bolt (explosion type) complying with GB22795 standard, manufactured from Q235 carbon steel, with a performance grade of 4.8 and color zinc plated surface. It is specially designed for high-altitude or top installation scenarios such as ceiling, curtain wall and pipeline suspension. Its extended design provides deeper anchoring depth and greater tensile strength. The explosion-type expansion structure can fully expand during fastening, generating strong friction with concrete and other base materials to achieve safe and reliable suspension fixation.
Core Advantages
-
High Load-Bearing and Tensile Strength: The extended design increases the anchoring depth, providing excellent tensile and shear strength, with strong load-bearing capacity.
-
Convenient and Reliable Installation: Adopting the principle of percussion-type or bolt explosion-type expansion, the expansion sleeve fully opens after installation, ensuring firm anchoring.
-
Suitable for Ceiling Installation: Specially designed for top and high-altitude suspension operations, it is a common fastener for ceiling projects.
-
Economical and Durable: Q235 material combined with color zinc plating ensures performance while having good cost advantages and rust resistance.
Applicable Industries
-
Building Decoration and Curtain Walls: Suspension installation of indoor and outdoor ceilings (such as mineral wool boards, aluminum gusset plates, grille ceilings), light curtain walls and decorative lines.
-
Electromechanical Pipeline Installation: Suspension and fixation of ventilation ducts, fire-fighting pipelines, cable trays, lamps, etc. on concrete floors or walls.
-
Indoor Partition and Suspension Systems: Top fixation of light steel keel partitions, exhibition suspension systems, and installation of large signs.
-
Infrastructure: Fixation of municipal guardrails, traffic sign pole bases, and small billboards on concrete foundations.
-
Warehousing and Logistics: Reinforced connection between the top of factory warehouse shelves and concrete structures, and auxiliary installation of crane rails.
Warm Tips
-
Before installation, please confirm that the strength of the base material (such as concrete) meets the requirements, and select the appropriate drilling diameter and depth.
-
Please use supporting installation tools (such as percussion mandrel or torque wrench) to operate in accordance with specifications to ensure that the expansion sleeve is fully opened.
-
The color zinc plating provides good rust resistance, but if used in extremely humid or corrosive environments, it is recommended to consult a higher-level anti-corrosion treatment plan.
