Product Introduction
Expansion bolt (also known as expansion bolt) is a type of fastener that relies on the expansion of expansion pipes to generate friction and achieve fixed connections. Its core is used to fix objects on substrates such as concrete, brick walls, and stone. With its convenient installation, stable load-bearing capacity, and wide adaptability, it is widely used in various scenarios such as building decoration, mechanical and electrical installation, municipal engineering, and home fixation. It has a simple structure, low cost, no need for complex construction tools, and can be quickly fixed. It is an indispensable basic connector in daily decoration and industrial installation, which can meet the fixing needs of light to medium heavy loads.
Core Strengths
● Easy installation and high efficiency: No need for complex construction equipment, just drill holes, insert expansion bolts, and tighten nuts to complete the fixation. It can be operated by a single person and is suitable for batch installation.
● Firmly fixed and stably loaded: The expansion tube is tightly attached to the substrate after being subjected to force, generating strong friction and excellent tensile and shear properties. It will not loosen or fall off after long-term use.
● Wide adaptability and diverse scenarios: It can be used for various substrates such as concrete, brick walls, stone, prefabricated panels, etc., taking into account the needs of light, medium, and heavy loads, and adapting to different industry scenarios.
● Simple structure, low cost: few components, mature production technology, high cost-effectiveness, can be purchased in bulk, suitable for large-scale engineering and daily decoration use.
● Complete specifications, customizable: Regular specifications are fully covered, supporting customized non-standard sizes, materials, and surface treatments to meet personalized fixed needs.
● Easy disassembly (some types): The nut can be loosened in the opposite direction to remove the screw, which is convenient for later maintenance and replacement without damaging the substrate (except for plastic expansion plugs).
Application Field
● Building decoration: installation of doors and windows, fixing of guardrails, ceiling keel, wall hanging, installation of air conditioning outdoor units, fixing of water heaters.
● Mechanical and electrical installation: fixing equipment such as distribution boxes, cable trays, pipe supports, water pumps, fans, etc.
● Municipal engineering: fixing street lamp brackets, traffic signs, monitoring equipment, guardrails, and billboards.
● Household daily use: fixing lightweight items such as hanging paintings, shelves, bookshelves, sinks, toilets, etc.
● Industrial production: workshop equipment, assembly line supports, storage shelves, and auxiliary fixation of heavy machinery.
● Other fields: Bridge auxiliary fixation, tunnel engineering, mining equipment, agricultural machinery fixation.
