T25 Rebar - 25mm High Tensile Reinforcement Bar
Alternative Names: T25 Rebar, H25 Rebar, 25mm Rebar, 25mm Reinforcement Bar, 25mm Steel Bar, 25mm Reinforcing Bar, Reinforcing Steel, Steel Reinforcing Bar, High Tensile Rebar, High Tensile Steel Bar, Deformed Bar, Ribbed Bar, Ribbed Steel Bar, Concrete Reinforcing Bar, Groundworks Steel, Steel Rod, Straight Bar, Stock Bar, Ground Beam Steel, Foundation Bar, Beam Reinforcement Bar, Column Bar, Structural Rebar, Heavy Duty Rebar, Commercial Rebar, Pile Cage Bar, BS4449 Rebar, CARES Approved Rebar
At 25mm, T25 rebar (also specified as H25) moves firmly into heavy structural territory. This high-tensile Grade B500B bar to BS 4449:2005 is specified where concentrated loads demand a substantial steel section: large columns, deep foundations and major frames. Bars of this size carry significant load, so they appear in commercial, civil and high-rise work far more often than in domestic projects, and are usually fabricated off site into cages and bent shapes ahead of the pour.
Typical applications
- Large columns and bored or driven piles
- Raft and basement foundations
- Commercial and high-rise frames
- Bridge and infrastructure works
- Heavy transfer beams
Why buy from Next Day Steel
Larger diameters like 25mm are kept in stock for fast dispatch in 6m lengths, fully CARES certified. Heavier bar is exactly where mill certification and CARES traceability matter most, and every T25 we supply carries both. Send your bending schedule and we will fabricate to your shapes. For heavy-frame projects, see our prefabricated cages and the wider rebar range.

T25 rebar: frequently asked questions
What is T25 rebar used for?
T25 (25mm) high-tensile rebar is used for large columns, bored piles, raft foundations and commercial frames. The ribbed profile bonds the bar to the concrete so the two work together under load.
What does the T in T25 mean, and is it the same as H25?
The T stands for high-tensile (high-yield) steel. T25, H25 and 25mm rebar all describe the same bar: Grade B500B deformed reinforcing bar to BS 4449:2005 with a 25mm nominal diameter.
How much does a T25 bar weigh?
A 6m T25 bar weighs 23.12 kg. Nominal mass for 25mm bar is shown in the comparison table above.
How much does 25mm rebar cost?
T25 rebar starts from £25.43 + VAT per bar, with current per-length prices shown above. Bulk-buy discounts apply automatically as weight is added to the cart, and cut and bent shapes are priced from your bending schedule.
What standard is T25 rebar manufactured to?
Our 25mm bar is Grade B500B high-tensile ribbed rebar to BS 4449:2005, CARES approved with full mill traceability. (Reinforcement is certified through the CARES scheme rather than CE marking, as EN 10080 is not a harmonised standard.)
