STEEL STRAND

  〓 PRODUCT FEATURES  

Flexible and high strength: multiple thin steel wires are twisted into a strand, which can be bent like a "steel rope" but can withstand great tension.

Special for prestressing: pre-apply tension to make concrete more crack-resistant and durable.

Lightweight and easy to operate: Compared with thick steel bars, it is light in weight and suitable for construction of complex shapes.

  〓 MAIN PURPOSE  

As the "invisible force" of prestressed concrete, it "tightens" the concrete in advance to enhance its bearing capacity.

  〓 APPLICATION SCENARIOS  

Long-span structure: main beams of railway overpasses and cross-sea bridges;

Complex construction: urban overpasses, expressways.

  〓 INSTALLATION POINTS  

Lubrication of bundles: apply special grease before inserting into the corrugated pipe to reduce friction resistance.

Timely grouting: pour cement slurry within 48 hours after tensioning is completed to fill the gap and prevent rust and corrosion.

End protection: After the exposed ends of the strands are locked with anchors, they need to be sealed with concrete to avoid rust.

Structural safety Intelligent tensioning eliminates human errors, ensures uniform distribution of prestress, and prevents bridge cracking and deformation	Efficient advancement Multi-equipment collaboration and automated operation shorten the construction period of large-span, multi-channel bridges.	Full-scenario coverage From coastal corrosive environments to extremely cold plateaus, the equipment can output stably, reducing engineering restrictions.	Low maintenance cost Highly durable materials and processes significantly extend the service life of bridges and reduce later maintenance investment

URBAN ELEVATED ROAD Lightweight jacks and low-noise pump stations to adapt  to nighttime construction and narrow space constraints
	CROSS-SEA BRIDGE Corrosion-resistant anchor and bellows combination  to resist high-salt environment
HIGHLAND RAILWAY Low-temperature electric pump stations and antifreeze  hydraulic oil for stable operation in extremely  cold environments
