PRODUCTS · SCREW PILES
Shafts, helical plates, flange heads and extensions made to your foundation design. A product image cannot confirm capacity, torque or corrosion life.
WHAT IS BEING MADE
A helical pile enquiry is manufacturable when the geometry is numeric. The shaft is a tube with an outside diameter, a wall and a length. Each helix has a diameter, a thickness, a pitch and a position along the shaft. The head is a flange, a plate, a U, or something that meets your column. Extensions and couplers exist only if the install length is longer than the piece you want to galvanize or ship.
RIBSPAN can coordinate those components against a drawing. The decision that the pile is adequate for the soil and the load belongs to the project engineer, using the ground investigation and the design method the project has adopted.
Without them, a price is a guess about a different pile.
A soil report, or the design parameters your engineer has already extracted from it. “Normal soil” and “similar to the last site” are not fabrication data. If the report cannot be shared, the engineer’s written pile schedule can stand in for it.
Compression, tension, lateral demand and the installation method: machine, torque indication, and any refusal rule. The head and the coupler have to survive installation, not only the in-service load.
Design life, coating system and any extra steel the engineer has added for section loss. Hot-dip after fabrication is a common request. It is not a substitute for the allowance the design requires.
WHAT THIS SUPPLY IS
The order can cover steel grade, weld quality as specified, dimensions, coating and packing. It should say who reviews torque records and who signs the foundation. Those are often the contractor and the engineer, not the steel supplier.
If you need a sample pile, define what the sample is for: fit of the head, a coating check, or a trial installation. A single trial does not create a general load rating for the next site.
Read the longer brief in what a screw-pile enquiry must contain. The same caution is in the project checklist.
No. Capacity depends on geometry, material, helix arrangement, installation and the ground. Those have to be assessed for the project.
No. If your engineer has specified a relationship between installation torque and capacity, send that instruction with the order. We will not invent one for the website.
Yes, when the coupler is drawn. Say the maximum piece length the galvanizing, the container and the site machine can accept. Those three limits are often different.
The drawing does. If it asks for a stated weld size and inspection level, that scope is quoted. A silent drawing does not imply a certified procedure.
