Adjustable Shore

Adjustable Shore - Professional Telescopic Steel Support System

Shandong Xingrui Building Materials Co., Ltd. manufactures premium Adjustable Shore systems engineered from Q235 structural steel with high-precision telescopic mechanisms. Our vertical support props deliver stable load-bearing performance up to 30kN (varies by extension height), featuring secure screw-locking systems and stepless height adjustment. Each unit undergoes ISO 9001-certified quality control with compression load testing at 3:1 safety factors. Manufactured across our 40,000-square-meter standardized workshops using 12 welding robots and 6 automatic production lines, these reusable props serve construction projects in over 100 countries. Available with hot-dip galvanization for 5-10 year service life in harsh environments.

What Is an Adjustable Shore?

The product systems function as heavy-duty telescopic tubular steel supports for temporary vertical shoring during construction. These engineered props support overhead loads including reinforced concrete slabs, beams, and formwork assemblies.

The telescopic design consists of inner and outer tubes with outer diameters ranging 48mm to 60mm. Wall thickness specifications from 1.5mm to 4.0mm accommodate varying load requirements. Thread mechanisms enable millimetric height adjustments across typical ranges of 1.6m to 5.0m.

This standardized support solution replaces traditional timber shoring methods. You gain reusable equipment with precise adjustment capabilities that ensure structural integrity throughout complex building operations.

Technical Specifications

Core Technical Advantages

Our manufacturing process integrates advanced production technology with strict quality protocols. The cold bending workshop utilizes 4 sets of precision forming equipment to maintain tube concentricity within tight tolerances.

Welding integrity receives dual verification through visual inspection and ultrasonic testing. The 12 welding robots in our automated lines produce consistent CO2 shielded joints at base plate and threaded sleeve connections. This ensures structural reliability under compression loads.

Surface treatment options include hot-dip galvanization tested via salt spray exposure. Magnetic thickness gauges verify coating micron levels that protect against corrosion in coastal or humid job sites. You receive props ready for long-term deployment without performance degradation.

The self-cleaning thread design of Adjustable Shore​ clears concrete splatter and debris during height adjustments. This practical feature maintains smooth operation throughout your project timeline while reducing maintenance requirements.

Primary Application Scenarios

Slab Formwork Support: High-rise residential and commercial construction relies on vertical props for horizontal formwork during concrete pouring. The stepless adjustment accommodates variable floor-to-ceiling dimensions across multiple levels.

Structural Renovation Projects: Restoration work requires temporary needle beam support when removing load-bearing walls or reinforcing foundations. Our props maintain existing structure stability throughout underpinning operations.

Trench Shoring Systems: Civil engineering projects deploy these supports horizontally or at angles to prevent soil collapse in excavations. The versatility extends to bracing vertical wall forms against wind pressure and lateral forces in underground environments.

The standard U-jack top fitting and square base plate interface seamlessly with steel formwork, aluminum formwork, and A-type beam systems. This compatibility streamlines integration into your existing support infrastructure.

Quality Control Process

Our 180 professional technicians implement full-process quality tracking across manufacturing stages. Raw material analysis begins with spectroscopic testing to verify carbon and manganese content meets ASTM and EN standards.

Compression load testing validates ultimate capacity ratings through both destructive and non-destructive methods. Digital calipers check tube wall thickness consistency and thread pitch accuracy to ensure reliable mechanical performance.

Each production batch undergoes dimensional tolerance verification. The complete traceability system documents inspection results from raw steel receipt through final shipment. This documentation supports your compliance requirements for international construction standards including EN 1065 and BS 4074.

Sample units are available for your evaluation. Our technical team provides specification guidance to match prop selection with your specific load requirements and project conditions.

FAQ

Q：How does extension height affect load capacity?

A：Load-bearing capacity decreases as the inner tube extends due to increased slenderness ratio. Always reference the manufacturer's load chart for precise height-to-weight ratings before deployment.

Q：What surface treatment should I choose?

A：Hot-dip galvanization provides cathodic protection ideal for long-term rental fleets and humid climates. Painted props offer cost-effective solutions for short-term indoor applications.

Q：Are base plates customizable?

A：Yes. While square plates come standard, flower plates and specialized U-head attachments are available to interface with timber or aluminum beam configurations.

Q：Which safety standards apply?

A：Our products comply with EN 1065 European standards for telescopic steel props and reference BS 4074 British standards to guarantee reliable performance under pressure.

Q：Can I order custom specifications?

A：Absolutely. We support made-to-order production based on your drawings and samples, leveraging our advanced forging and stamping workshops to meet unique project requirements.
