M350 Concrete (B25)
A grade for multi-storey frame buildings and heavily loaded structures
M350 (class B25) is intended for the frame elements of multi-storey buildings — columns, beams, shear walls and heavily loaded floor slabs. Its 25 MPa strength makes it the standard choice of design engineers for multi-storey residential and commercial projects.
For construction companies we organize M350 supply on schedule, with an uninterrupted mixer flow — your pour shifts never stop. Production follows GOST 26633, with laboratory control and 28-day cube testing.
Applications
Multi-storey frames
The design standard for columns, beams and shear walls.
Heavily loaded slabs
Reliable strength for long-span monolithic slabs.
Commercial projects
Monolithic work for shopping centers and office buildings.
Continuous supply
A scheduled, uninterrupted concrete flow throughout the project.
Concrete grades we produce
All grades are produced to GOST 26633 requirements. See all grades →
Frequently Asked Questions
Where is M350 concrete used?
Frames of multi-storey buildings (columns, beams, shear walls), heavily loaded floor slabs, long-span slabs and monolithic structures of commercial projects.
What is the difference between M350 and M300?
M350 (B25, 25 MPa) is stronger than M300 (B22.5, 22.5 MPa) and is chosen when the design loads are higher. The structural engineer determines which one is required — if you have no design, tell us about the project and we will advise you.
What are the terms for large-volume M350 orders?
For multi-storey projects we set up a continuous supply schedule and offer special commercial terms based on volume. Tell us the total volume of the project — we will prepare a contract-based offer.
Can M350 be placed with a pump?
Yes, the M350 mix is prepared to be pumpable — for pouring at height you can order pump service together with the concrete.
