Hyprescon is the exclusive manufacturer and supplier of precast Hy-Span structures in Ontario. The table illustrates available dimensions of Hy-Spans units. Larger dimensions of span and rise are available upon request. All Hy-Span structures are designed in accordance to the OHBDC-91 and are fabricated to OPSS material and construction specifications.

A Hy-Span unit is designed as a three member rigid frame with hinged supports at the basis of the legs. Thus, the entire structural unit is subjected to bending moments where the deck experiences moments that are smaller in magnitude compared to a conventional structure. Therefore, the slab thickness of Hy-Span structures can be reduced, permitting a smaller, more efficient structural element. The application of a rigid frame structure also means that no additional lateral restraints are required.

Design and Economical Advantages

1. Quick and easy installation keeps project turn-around time at a minimum and the budget in line.
   
   
2. The application of high performance concrete provides a stronger and denser cement matrix in concrete allowing for greater durability.
   
   
3. The fabrication of precast Hy-Span units generally occurs during the construction of the footings; thus, ensuring a continuous and a much shorter construction cycle of the bridge project.
   
   
4. All precast Hy-Span units are designed without shear keys between the units to provide a quicker and easier installation.
   
   
5. Hy-Span structures facilitate phased-construction while maintaining the traffic.
   
   
6. The use of precast Hy-Span units allows construction of creek overpasses without disturbing the natural flow of the creeks.
   
   
7. The rigid frame design provides less restrictive cover limitations.
   
   
8. Normal backfill procedures are acceptable; thus, no additional lateral resistant is required.
   
   
9. The span, rise, laying length can be varied in almost any dimension and combination.
   
   
10. Our manufacturing facility provides great flexibility to meet all your project requirements.
    
    
11. High quality assurance ensures longer life and performance of the structure.
    
    
12. The application of concrete provides a longer life and less maintenance compared to other materials such as steel.
