Adjustable Steel Prop For Bridge Construction And Heavy Duty
Formwork
Adjustable Steel Prop (also known as Acrow Prop or Telescopic Steel
Shore) is a critical vertical shoring component used to support
slabs, beams, and formwork during concrete pouring. Consisting of
an outer tube, inner tube, and threaded adjusting mechanism, it
provides robust temporary support for construction and renovation
projects, ensuring safe load transfer and precise height alignment.
Key Features & Functions
- High Load-Bearing Capacity: Manufactured from high-tensile steel
(Q235/Q345), it offers a safe working load (SWL) typically ranging
from 20 kN to 35 kN, ensuring stability under wet concrete pressure
and construction loads.
- Precise Height Adjustment: Features a dual adjustment system with
pin holes for coarse setting and a threaded collar for fine-tuning,
allowing millimeter-level accuracy to achieve perfect slab
leveling.
- Durable & Reusable: Hot-dip galvanized or painted finish provides
excellent corrosion resistance, enabling dozens of reuse cycles
across multiple projects with minimal maintenance.
Technical Parameters
- Height Range: Standard models cover 1.6-3.0 m (light duty) to
2.5-5.0 m (heavy duty); custom lengths available.
- Tube Specifications: Common configurations include 48.3mm inner /
60.3mm outer tube; wall thickness 2.0-3.0 mm.
- Standards Compliance: Designed and tested in accordance with EN
1065, BS 4074, or AS/NZS 1577 for shoring safety.
Competitive Advantages
Our Adjustable Steel Props are engineered with full-penetration
welding and cold-rolled threads for maximum joint strength.
Compared to traditional pipe scaffolding, they require 30-50% fewer
units per square meter, drastically cutting labor and transport
costs while providing certified load capacity for high-rise
buildings, bridges, and civil engineering projects.

Frequently Asked Questions
Are you a trading company or a manufacturer?
We are a subsidiary foreign trade company of a group company,
mainly responsible for operating the export business of formwork
and scaffolding products. Our group company has two major
production bases specializing in production and processing for over
20 years.
How can I get a quotation?
For simple concrete pouring projects with your own engineer,
provide a bill of materials for quotation. For complex projects
requiring plastic formwork, our consultants will communicate with
you and develop application plans based on engineering drawings.
How long does it take to complete the plan and quotation?
Generally takes about 5-8 days to complete specific plans and
detailed quotations after receiving engineering drawings.
Can you provide free samples?
Yes, we can provide samples. You will need to pay for the shipping
cost.
How long is the estimated delivery time?
According to project complexity, usually takes 30-60 days to
complete stocking. More accurate delivery times are estimated
during planning and quotation.
Is the plastic template prone to deformation?
In long-term high temperature environments, concrete pouring may
cause slight deformation. We recommend using aluminum alloy
formwork or steel frame wood formwork systems in high temperature
areas.
What are the defects of the plastic template system?
Limited load capacity for large-sized concrete structures and poor
high temperature resistance with potential deformation in
high-temperature areas.
What is the payment method you require?
Payment ≤1,000 USD: 100% in advance. Payment ≥10,000 USD: 30% T/T
in advance, balance before shipment. Or L/C.
