Adjustable steel props Sizes 0–4 • Heights from 1.04m to 4.87m • Powder-coated green finish for corrosion resistance & durability • BS4074 & BS5507 compliant • Secure prop pin locking • Essential for temporary support of ceilings, RSJs, steel beams, floors, formwork & load-bearing walls • Ideal for construction, repairs, beam removal & shoring • High-quality new stock
We offer a full range of adjustable Acrow props (also known as steel props, shore props, jacks, or struts) in sizes 0 through 4—the trusted choice for reliable temporary support in UK construction, renovation, and repair projects. Manufactured from durable steel, these props provide essential vertical shoring for ceilings, floors, RSJs, steel beams, lintels, load-bearing walls, formwork, and openings, helping to maintain structural stability while work is carried out.
As experienced suppliers operating since 2012 from our West Sussex base, we source only high-quality Acrow props finished in powder-coated green or red. These props are manufactured to meet relevant British Standards, including BS 4074:1982 and BS 5507-3:1982, ensuring reliable compressive strength and performance. The powder-coated finish offers excellent corrosion resistance, making them suitable for both indoor and outdoor use in demanding site conditions across the UK.
Our range covers a wide variety of extension heights to suit most applications:
Whether you’re a builder removing beams, a contractor installing lintels, or managing formwork on a development, these reusable, easy-to-adjust props deliver the strength and flexibility required for safe, compliant temporary works. Always follow TG20:21 guidance or site-specific engineering designs for correct spacing, load distribution, and inspection regimes.
We offer fast delivery (typically 2–5 working days) or collection by appointment from our Aldingbourne yard. Bulk and trade orders are welcome, with discounts available for larger quantities.

| Size | Typical Height Range | Common Applications | Key Benefit |
| 0 | Lower-level | Ceilings, floors, light walls, formwork | Compact for tight spaces |
| 1 | Mid-range | RSJs, lintels, beams in extensions/repairs | Versatile for standard openings |
| 2 | Mid-to-tall | Load-bearing walls, beam removal | Balanced strength & reach |
| 3 | Tall | Higher floors, heavier shoring | Extended support without excess weight |
| 4 | Maximum | Tall structures, deep basements, heavy loads | Most extended reach for demanding sites |
Acrow props (also called adjustable steel props, shore props, jacks, or struts) are versatile temporary vertical supports used in construction to safely hold up ceilings, floors, RSJs, steel beams, lintels, load-bearing walls, formwork, and openings during building, repairs, beam removal, or shoring. Our experienced team has been supplying these since 2012. We recommend them for any project that needs reliable, reusable propping, which is always part of a competent temporary works design per UK guidelines, such as TG20:21.
We stock the full standard UK range: Sizes 0 to 4, covering extension heights from around 1m to nearly 5m. Choose based on required height and load: smaller sizes (0–1) suit lower-level or lighter propping; larger (3–4) for taller/heavier applications. Consider your project’s vertical clearance and consult a structural engineer for spacing/load distribution. Our powder-coated props offer excellent corrosion resistance for site conditions.
Factor | Why It Matters | Recommendation / Best Practice |
Height Requirement | Must match clearance without over-extension | Select size covering needed range; avoid max extension for stability |
Load Type & Distribution | Prevents overload/failure | Engineer-assessed; even spacing (e.g., ~1m centres typical) |
Environment | Corrosion risk in wet/outdoor sites | Powder-coated for durability; inspect regularly |
Standards Alignment | Ensures safety/compliance | Aligned with BS 4074/BS 5507; follow TG20:21 guidelines |
Inspection & Use | Detects issues early | Check before use; temporary only—never permanent without engineer approval |
Yes, our high-quality props comply with BS 4074:1982 (for props) and BS 5507-3:1982 (for compressive strength testing), which are standard benchmarks for safe temporary supports in the UK. We prioritise durable, powder-coated steel sourced from trusted suppliers to ensure reliability in real construction environments. For full compliance on your site, follow engineering guidance and regular inspections.
Steel Acrow props are adjustable, reusable, strong, and quick to install compared to timber alternatives (which rot or burn easily). Powder coating protects against rust in outdoor/wet conditions, and the pin-locking system securely holds extensions. Based on our hands-on experience, they’re cost-effective for trade users, with bulk discounts and nationwide delivery.
As a general industry rule, space props evenly at around 1 metre centres for many applications (e.g., supporting floors or walls), but increase density for heavier loads like masonry or brickwork. Spacing must be verified by a structural engineer based on exact loads and site conditions – never assume; improper spacing risks failure.
Absolutely, the powder-coated finish provides strong corrosion resistance, making them ideal for exposed sites, damp basements, or indoor renovations. They’re built for repeated use across the UK.
Always use as temporary supports only; inspect before/after each use; ensure level/plumb installation; and never exceed recommended loads (consult engineer). Regular checks for movement or loosening are essential. As experts, we always stress professional oversight.
Application | Recommended Size(s) | Typical Spacing | Notes / Pro Tip from our team |
Supporting RSJ / steel beams | 2 or 3 | 900mm–1.2m | Use strongboys for needlework |
Shoring load-bearing brick walls | 2 or 3 | 800mm–1m | Double up on heavy Victorian walls |
Floor/ceiling propping | 1 or 2 | 1–1.5m | Ideal for house extensions |
Formwork support | 2, 3 or 4 | As per the engineer | Pair with fork heads & timber |
Basement/tank shoring | 3 or 4 | 800mm–1m | Size 4 essential for deep excavations |
Lintel installation | 1 or 2 | 600–900mm | Quick & easy for most domestic openings |
Note: Always consult a structural engineer; the above is only a guide.
Accessory | Purpose / When to Use | Benefit / Pro Tip from Our Team |
Strongboy / Needle Heads | Supporting walls during openings (e.g., doors/windows) | Distributes load across brickwork; use pairs under timber needles for an even spread |
U-Head / Fork Heads | Formwork or beam support | Secures timber bearers; ideal for concrete pours or lintel placement |
Sole Plates / Base Boards | Soft or uneven ground (e.g., soil, timber floors) | Prevents sinking; always use on unstable surfaces for stability |
Scaffold Tubes & Fittings | Lateral bracing to prevent sway | Essential for taller props (>3m); tie back to structure |
Adjustable Heads / Swivel | Uneven ceilings or angled loads | Allows fine levelling; reduces eccentricity risk |
Check Item | What to Look For | Action if Issue Found | Frequency (Our Recommendation) |
Powder Coating / Surface | No excessive rust, dents, or flaking | Clean lightly; replace if severe corrosion | Before every use |
Threads & Collar | Smooth winding, no stripped threads or binding | Lubricate if stiff; replace if damaged | Before every use |
Pins & Holes | Pins secure, holes not elongated or cracked | Replace pin/prop if worn | Before every use |
Base & Top Plates | Flat, no bending; clean contact surfaces | Straighten if minor; replace if deformed | Before every use |
Overall Straightness | Prop plumb (use level); no bowing | Do not use if bent; return for inspection | Before & during use |
Load History | No signs of overload (e.g., deformed sections) | Retire from service | Ongoing monitoring |
This is general guidance based on industry best practices. Always follow manufacturer instructions and have props professionally inspected periodically.
