Definition of Steel Shoring System:

The Steel Shoring System is a temporary vertical support used in construction and excavation, consisting of an Inner Tube and Outer Tube with a Head Jack (U-Head/Flat Plate) at the top and a Base Plate at the bottom. 

Height is set via a Clevis Pin for rough adjustment and a threaded Adjustable Nut for fine tuning. Primarily utilized for formwork support during concrete pours and aslateral struts in foundation pits, the system offers high load capacity and rapid deployment, with Tripods ensuring stability against overturning. 

Proper selection requires verifying the prop's bearing capacity and stroke against project specifications.

Specifications of Steel Shoring System: Flexible OEM Customization

Below are conventional specifications; please feel free to inquire for any special load or length requirements.

The adjustable height, wall thickness, tube diameter, and load-bearing capacity of our steel shoring system fully comply with Chinese industrial standard. While maintaining high-volume production quality, we offer in-depth OEM customization services. We can flexibly adjust tube wall thickness and surface treatment according to your drawings or specific job site requirements. 

System Components of Steel Shoring System:

Note: All dimensions and load capacities must comply with local engineering standards and project specifications.

The Steel Shoring System typically consists of the following core components:

1. Head Jack (Top Support): 

Located at the top of the inner tube, used for direct contact and securing of formwork or beams. Common types include Square Plate and Flower Type.

2. Support Head Assembly: 

Connects the support prop to the formwork or beam above and safely transfers the load downward. Common types include U-Head and Four-Way Fork Head.

3. Main Prop Body: 

Comprised of an Inner Tube (Intubation) and an Outer Tube (Sleeve) . Rough and fine height adjustment is achieved through the combination of a Clevis Pin and an Adjustable Nut.

5. Base Plate: 

Located at the bottom of the outer tube, used to uniformly transfer the load to the ground or lower slab. Flat Base Plates are common.

6. Tripod: 

A tripod brace component located at the bottom of the independent steel prop, used to stabilize the vertical member.

Applications of Steel Shoring System in Civil Engineering:

Due to its high load-bearing capacity, ease of erection/dismantling, and versatility, Steel Shoring System is primarily used in the following scenarios:

1. Formwork Engineering: 

Vertical support during concrete pouring of floor slabs and beam soffits. Check the applications with our PVC plastic formwork:

2. Foundation Pit and Slope Support: 

Used as horizontal struts or rakers to resist lateral earth pressure.

3. Steel Structure Installation: 

Providing temporary positioning and stabilization during hoisting operations.

4. Emergency and Remedial Works: 

Rapid temporary lifting or propping during structural damage or renovation.

The core advantage of Steel Shoring System system lies in its adjustability and self-stability. Coarse adjustment is achieved rapidly via the locking pin across the tube perforations, while fine, millimeter-level elevation adjustment is achieved by rotating the exposed threaded nut. 

This ensures tight contact between the head jack and the formwork. The use of tripods or horizontal lacing prevents single-prop overturning, establishing a stable structural frame.

Why Choose Our Steel Shoring System?

1. Superior Craftsmanship & Quality Control: 

Precision-processed details with reinforced welds ensure exceptional joint strength and structural integrity.

2. Post-Weld Galvanizing, Not Pre-Galvanized Tube: 

We insist on post-fabrication galvanizing rather than using cheap pre-galvanized tubes. With pre-galvanized material, the zinc coating is completely destroyed at every cut and weld joint, leaving bare steel exposed and prone to immediate rusting. 

Our post-weld galvanizing process ensures that every weld seam, inside and out, is fully encapsulated in a continuous zinc layer — eliminating the risk of rust starting at the joints from day one.

3. Eco-Friendly Alkaline Zinc Plating: 

Features a bright, tarnish-resistant finish utilizing alkaline zinc plating (NSS test >72 hours). This surpasses standard acidic zinc plating (often <24 hours), preventing premature darkening or corrosion.

4. 70%+ Zinc Content — No Rapid Tarnishing: 

We utilize premium-grade steel with a zinc content exceeding 70% in the coating, ensuring long-term color retention and gloss. Inferior alternatives often contain less than 30% zinc (with high aluminum content), leading to rapid tarnishing.

5. Heavy-Duty Components: 

Equipped with Grade 8.8 nuts, oversized tube diameters, and enhanced U-Head dimensions (width, flange height, thickness). All components exceed standard specifications to guarantee superior load-bearing capacity.

6. Reinforced Weld Reinforcement to Fork Head Welding-Eliminating Hidden Risks: 

Our Four-Way Fork Head strictly adheres to load-bearing weld standards. The joints are executed using a non-parallel welding technique with an intentionally retained reinforced weld reinforcement (weld cap). 

This significantly enhances the joint's tear resistance, ensuring the structure is engineered for more scientific load distribution and superior stability. We refuse to grind down or thin out the weld joint merely for a smooth appearance.

7. Precise Tube Thickness, Zero Compromise: 

We enforce strict wall thickness tolerances with deviations controlled within 1mm. No material cutting corners—ensuring the delivered weight precisely matches client specifications.

8. Acrylic Enamel Finish, Superior Weatherability: 

We apply a high-quality acrylic paint finish that remains glossy and tarnish-free for 5-7 years. Unlike low-grade water-based paints used by others—which fade or chalk within hours of sun exposure—our coating withstands harsh job site conditions.

9. Expert-Led Support: 

Behind every product is a team that knows both engineering and global markets. Our senior engineers bring 28+ years of hands-on experience in formwork and shoring design, while our international trade specialists contribute 15+ years of export expertise. Together, they ensure you receive expertly crafted products — delivered on time, documented correctly, and tailored to your market.

FAQ About Our Steel Shoring System

Q: What quality standards does your steel shoring system comply with?

A: Our steel shoring system's adjustable height, wall thickness, tube diameter, and load-bearing capacity fully comply with Chinese National Standards (GB). Moreover, we enforce strict wall thickness control with deviations within 1mm — absolutely no material compromise — ensuring the weight and performance of every batch precisely match customer specifications.

Q: Why do you use alkaline zinc plating instead of standard acidic zinc plating?

A: Alkaline zinc plating offers superior corrosion resistance and a brighter, more uniform finish. Our NSS (Neutral Salt Spray) test rating exceeds 72 hours, ensuring a dense, long-lasting bright finish. In contrast, standard acidic zinc plating typically achieves less than 24 hours in NSS testing and tends to tarnish or rust within months outdoors. For long-term reuse, alkaline zinc plating provides far better value.

Q3: What is the zinc content of your coating, and what are the advantages?

A: We use premium-grade steel with a zinc content exceeding 70% in the coating, ensuring long-term gloss retention and color stability. Inferior alternatives often contain less than 30% zinc (with high aluminum content), leading to rapid oxidation and tarnishing. Our high-purity zinc coating is the core guarantee behind our props' 5–7 years of tarnish-free performance.

Q4: What are the benefits of the acrylic enamel finish on your steel props?

A: We apply an acrylic enamel finish that delivers a high-gloss, durable coating with excellent weatherability and UV resistance. Unlike low-grade water-based paints — which can fade or chalk within hours of sun exposure — our acrylic enamel stays glossy for 5–7 years without fading or powdering. Combined with an alkaline zinc-plated base, this dual-layer protection keeps the props looking new even under harsh outdoor conditions and frequent reuse.

Q5: What is special about the welding technique on your 4-Way Fork Head?

A: We employ a non-parallel welding technique with an intentionally retained reinforced weld reinforcement (weld cap). This raised bead, deliberately left unground, compensates for strength loss in the heat-affected zone, significantly enhancing tear resistance and structural stability. We refuse to grind down the weld simply for a smooth look, as this is often used in the industry to hide weak, superficial welds.

Q6: Do you support OEM customization for tube diameters, wall thickness, height ranges, and surface treatments?

A: Yes, we offer in-depth OEM customization services. Whether you require light-duty tubes (48mm/56mm), heavy-duty options (60mm), specific wall thicknesses (1.6mm – 4.0mm), non-standard height ranges, or different surface finishes (painted/galvanized/acrylic enamel), we can flexibly adjust to meet your specifications. Simply send us your technical requirements, and our engineering team (28+ years of experience) will calculate the optimal solution for you.
