The steel stirrup used in construction is an indispensable supporting component in the field of building construction, primarily employed during reinforced concrete structure work. It provides stable support for the upper-layer reinforcement bars, ensuring that the rebar spacing adheres to design specifications and ultimately guaranteeing the structural strength and overall quality of the concrete-cast elements. Manufactured through precision processes and subjected to rigorous quality inspections, this product is perfectly suited for a wide range of construction scenarios, offering robust assurance for both project safety and efficiency.

Product Core Parameter Table

Product Advantages

1. High-strength material, exceptional safety performance

Using Q235 low-carbon steel or Q345 alloy steel as raw materials, the material undergoes professional melting and rolling processes, resulting in high purity and minimal impurities—ensuring superior product strength right from the source. The finished products are either fully stamped into shape or reinforced through welding, creating a structurally robust design with outstanding resistance to bending and shear forces. Withstanding static loads of up to 500 kg or more, these components can effectively support the weight of upper reinforcement bars as well as temporary loads during construction, preventing issues like bar deformation or displacement caused by failure of supporting elements—and ultimately reducing risks to overall project quality.

2. Precision craftsmanship—details define the quality.

The product is manufactured entirely using an automated assembly line, with dimensional accuracy maintained within ±2mm. This ensures consistent specifications across different batches, making it perfectly suited for standardized construction processes. The top support surface has been meticulously ground and chamfered to eliminate any sharp burrs, effectively preventing scratches that could damage the rust-proof coating on reinforcing steel during installation. Meanwhile, the bottom base features an expanded and thickened design, significantly increasing its contact area with the formwork and enhancing overall support stability. Additionally, the surface treatment options are versatile: hot-dip galvanizing provides exceptional corrosion resistance, extending the product's lifespan beyond 5 years; while cold-galvanized and painted finishes are ideal for dry construction environments, meeting the specific corrosion-resistance requirements of various application scenarios.

3. Easy installation, boosting construction efficiency

The product features an integrated structural design, eliminating the need for complex assembly. At the construction site, installation can be completed simply by placing the components directly according to the rebar spacing—allowing a single worker to install 500 to 800 units per day. This significantly boosts construction efficiency by more than 60% compared to traditionally handcrafted stirrups. Additionally, the product is lightweight (weighing just 0.3–1.5 kg per unit), making it easy to handle and transport, while also enabling flexible deployment based on project progress. What’s more, the product is compatible with a wide range of rebar specifications, so there’s no need to switch support components for different rebar diameters, further reducing preparation time on-site.

4. Highly compliant, tailored to diverse needs

Product manufacturing and testing strictly adhere to national construction standards such as JGJ 18-2012 and GB 50204-2015. Each batch of products comes with a comprehensive quality inspection report, including material certifications and load-bearing test data, ensuring they are ready for direct use in project acceptance. We also offer personalized customization services: based on customers' construction drawings, we can tailor products with varying heights, support widths, and surface treatment processes to meet the specific needs of projects like bridges, tunnels, and high-rise buildings.

Application Scenarios

1. Civil Construction Site Scenarios

In the construction of reinforced concrete structures such as floor slabs, balconies, and terraces in residential buildings, office complexes, commercial spaces, and other civil constructions, this product effectively supports the upper-layer reinforcing bars, ensuring that the concrete cover thickness meets design specifications—typically ranging from 15 to 25 mm. This helps prevent issues like slab cracking and insufficient load-bearing capacity caused by bar下沉 (bar sinking). Given the relatively thin floor slab thicknesses commonly found in civil buildings (usually between 80 and 120 mm), we recommend using products with a height specification of 50 to 100 mm. These can be paired with either cold-galvanized or spray-painted surface treatments, striking a balance between cost-effectiveness and corrosion protection needs.

2. Bridge and Tunnel Engineering Scenarios

During the construction of bridge decks, piers, tunnel linings, and other structural elements, reinforcement bars are densely arranged, demanding high load capacities. Moreover, construction environments are often exposed to outdoor or humid conditions, placing stringent requirements on the strength and corrosion resistance of stirrups. This product is crafted from Q345 alloy steel and features a hot-dip galvanized surface treatment, effectively safeguarding against erosion from rainwater and groundwater, with an anti-rust lifespan exceeding 5 years. We recommend selecting products with heights ranging from 125 to 200 mm, perfectly suited to support reinforcing bars in thick-section concrete structures commonly used in bridges and tunnels (typically 300–800 mm). This ensures uniform spacing of reinforcement bars, thereby enhancing the structure's shear and flexural performance.

3. Industrial Construction Site Scenarios

In the construction of industrial buildings such as factories, warehouses, and workshops—specifically for flooring, roofing, and load-bearing beams—the structures often need to withstand heavy equipment and cargo loads, placing extremely high demands on the strength of reinforced concrete frameworks. This product offers a single static load capacity of ≥500 kg, effectively supporting densely arranged heavy-duty reinforcing bars (φ25–φ32 mm) without causing deformation during construction. Given the long construction timelines and complex environmental conditions typical of industrial building projects, we recommend using products with hot-dip galvanized surface treatment to enhance durability in harsh environments. Additionally, we can customize products with specific heights tailored to the unique cross-sectional dimensions of load-bearing beams and columns, ensuring superior construction quality.

4. Municipal Engineering Construction Scenarios

During municipal construction projects such as roads, sidewalks, plazas, and underground parking lots—where construction areas are large and project timelines are tight—the demand for efficient and cost-effective installation of stirrups is particularly high. This product is easy to install, enabling a single worker to assemble up to 800 units per day, significantly accelerating the construction process. Considering the outdoor nature of municipal engineering projects, products with either cold-galvanized or hot-dip galvanized surface treatments are ideal choices, offering superior resistance against weathering and environmental elements like rain and wind. We recommend selecting products with heights ranging from 75 to 150 mm, which perfectly match the thickness of common concrete structures used in municipal projects—typically 100 to 300 mm—and ensure that construction quality meets rigorous municipal standards.
