All its components and connection joints feature rigid designs, forming a stable, integrated unit through welding or high-strength bolting. This structure provides robust load-bearing capacity and omnidirectional rigid restraint, strictly limiting displacement and deformation in any direction. It is suitable for supporting single pipelines characterized by large diameters, heavy loads, or stringent spatial positioning requirements, and is commonly found in industrial fixed pipe supports or structural transition zones where thermal displacement compensation or vibration isolation is not required.

A rigid multi-pipe gantry is an overhead, portal-style steel structure designed to provide centralized and stable support for multiple parallel pipelines. All connection joints are rigid—utilizing welding or high-strength bolting—creating a robust, unified framework. This structure offers exceptional load-bearing capacity and overall stability, strictly limiting spatial displacement of the pipes to ensure precise alignment and safety under complex operating conditions. It is suitable for industrial applications requiring rigorous pipe positioning—such as pipe racks in large-scale plant areas or rows of process piping—where the pipes themselves can withstand thermal stresses and allow for vibration transmission.

A rigid rectangular duct gantry is a robust, portal-style support structure designed to carry rectangular-section ducts. Its main framework—comprising uprights and crossbeams—is assembled using welded or bolted rigid connections, while the connection between the crossbeam and the duct also employs rigid clamping. This structure offers exceptional stability and load-bearing capacity, effectively restraining duct displacement in any direction; it is suitable for applications requiring precise duct positioning where thermal expansion compensation is unnecessary and vibration transmission is permissible, such as rigid ductwork systems for ventilation or dust extraction in industrial facilities.

Flexible single-pipe suspension is a simple method for supporting suspended piping, typically consisting of a suspension rod paired with a flexible component (such as a spring hanger or rubber vibration isolator). Its primary function is to suspend an individual pipe while utilizing the elastic deformation of the flexible element to effectively absorb and isolate displacements and stresses caused by thermal expansion and contraction, equipment vibration, or impact. This method offers installation flexibility and significantly reduces vibration transmission and operational noise within the piping system; it is commonly used in HVAC systems, power piping, and at the ends of branch lines requiring independent vibration isolation.

A flexible single-pipe gantry is a portal-style steel frame structure designed to support a single pipeline. Its "flexibility" stems from the use of elastic components—such as spring hangers—to connect the pipeline to the crossbeam; this allows for controlled axial or lateral displacement of the pipe during thermal expansion/contraction or under external forces, thereby effectively relieving stress and isolating vibration and shock. This structure protects the piping system by preventing damage caused by rigid constraints and reduces operational noise, making it particularly suitable for applications requiring vibration damping and displacement compensation, such as thermal pipelines and the inlet/outlet connections of vibrating equipment.

A flexible multi-pipe gantry is an overhead portal structure designed to provide centralized support for multiple parallel pipelines. Its key feature is the incorporation of a series of flexible hangers (such as springs or rubber vibration isolators) along the crossbeam, enabling the independent absorption of thermal displacement, mechanical vibration, and shock for each individual pipe. This design effectively prevents the mutual transfer of stresses between pipes, significantly reduces operational noise, and ensures system safety. Widely utilized in complex piping layouts within the chemical, energy, and precision manufacturing sectors, it serves as an ideal solution for vibration reduction and isolation management in multi-pipe systems.

A flexible rectangular duct gantry is a structure designed to support and secure ducts with rectangular cross-sections. Its "flexible" design incorporates adjustable or resilient components—such as spring hangers or rubber pads—at connection points to accommodate thermal expansion and contraction, vibration, or slight displacements, thereby effectively reducing stress. This structure protects the ductwork system and minimizes noise transmission, making it widely applicable in HVAC systems, power piping, and industrial sectors with specific vibration-dampening requirements.

A dual-column riser support is a common piping support structure consisting of two parallel vertical columns connected by crossbeams or mounting fixtures. Its design offers excellent stability and load-bearing capacity, effectively withstanding vertical loads, horizontal forces, and vibrations. Facilitating the installation, adjustment, and maintenance of piping, this structure is widely used in industrial facilities, municipal projects, and building water supply and drainage systems; it is particularly suitable for supporting critical pipelines—such as large-diameter pipes or those requiring long-distance overhead routing.

A rigid single-pipe support is a structural component designed to support and secure piping; it is fabricated from rigid materials (such as steel) and features a single tubular main body. Characterized by a simple structure, high load-bearing capacity, and ease of installation, it is suitable for a wide range of industrial and architectural piping systems. This support effectively restricts pipe displacement and minimizes vibration, ensuring the stability and safety of the piping layout, and is widely used in sectors such as HVAC, water supply and drainage, and electrical piping systems.

A lateral seismic brace for cable trays is a specialized seismic component designed to resist horizontal lateral forces generated during an earthquake, thereby preventing the cable tray system from shifting laterally or overturning. It typically consists of an anchor rigidly connected to the building structure, a diagonal brace capable of withstanding both tension and compression (such as a combination of C-channel steel and threaded rods), and a specialized clamp connecting to the cable tray, forming a stable triangular support system. Designed and installed in accordance with national seismic design codes, this brace effectively restrains lateral displacement during seismic events, safeguarding the safety and continuous operation of power and communication lines; it is a critical component of seismic protection systems for mechanical and electrical installations in modern buildings.

A bidirectional seismic support for cable trays is a specialized device designed to provide seismic restraint in two directions (typically the horizontal X and Y axes) for cable tray systems. By establishing multi-point, multi-directional rigid or flexible connections between the cable tray and the building structure, it creates a spatially stable system. Typically composed of combined longitudinal and transverse seismic braces, specialized connectors, and anchors, the support effectively absorbs and dissipates seismic energy. It limits horizontal and lateral displacement and swaying, preventing the system from detaching or collapsing, thereby ensuring the safety and functional continuity of critical power and communication lines during an earthquake; it is a key component in high-standard seismic-resistant mechanical and electrical installations.

A multi-pipe lateral seismic brace is an integrated seismic support system designed to simultaneously restrain multiple parallel pipes in the horizontal (lateral) direction.
