Structural Plate

Unlike corrugated steel pipe, corrugated steel structural plate (SSP) is shipped to the site in curved plates and field assembled into its final shape by bolting. When spans exceed 12 feet, SSP may become the best corrugated steel option. Without shipment limitations associated with large conventional pipe, combined with increased thicknesses (through 1 gage) and stiffer corrugations, SSP expands the number of useful applications otherwise unattainable, and allows corrugated steel to be a viable alternative to the one or two options historically available in certain situations.

Pacific Corrugated Pipe supplies both steel and aluminum structural plate so engineers, developers and contractors have a choice. The lighter weight of aluminum plate creates a significant handling advantage. Aluminum is durable, offering excellent resistance against the effects of corrosion and abrasion.

Integrating an aluminum structural plate headwall into a selected culvert size and shape creates an installation friendly bridge replacement solution. With no rebar schedules, mix specifications, pours, frequent testing, cure times, etc., aluminum structural plate headwalls are an economic alternative to concrete.

The Benefits
  • Lightweight— compared to other types of structures of similar size, such as structural steel or concrete bridges.
  • Strong— the 6″ x 2″ (steel) and the 9″ x 2.5″ (aluminum) corrugations are significantly stronger than other corrugations of the same thickness.
  • Easily installed— light equipment, simple tools and unskilled labor under adequate supervision can easily complete the assembly.
  • Made to last— our steel structural plate is protected by a 3-ounce zinc coating, which gives the structure a long life with 50% more zinc than regular corrugated steel pipe.
  • Conveniently delivered— plates are shipped in compact nested bundles, minimizing handling and freight costs.

Welded Wire Mesh Gabion & Gabion Mattresses

These flexible, permeable, rock-filled and interconnected modular units create a monolithic wall for earth retention or a blanket for soil stabilization, providing the civil engineer a unique building material that aesthetically blends that sheared-rock look into its natural environment.

Welded wire mesh means that each point of contact in the grid is welded to form a more rigid connection, making this type of gabion indispensable in achieving a more flat, sharp appearance. The added stiffness makes rock filling less cumbersome for better installation times and reduced labor costs.

PRE-ASSEMBLED
Our gabions are shipped flat (i.e. collapsed) with hinged panels that easily fold into a rectangular basket. Sides are raised, and the seams temporarily fastened. The basket is placed, and adjacent edges permanently laced.

QUICKER ASSEMBLY
Once expanded and placed, gabions are simply and securely interconnected with corkscrew spiral binders at each vertical junction. Welded wire mesh gabions are assembled, placed and filled considerably faster than their woven wire counterparts.

 

BETTER SHAPE CONTROL
Welded wire mesh provides shape control superior to twisted or woven wire fabric. Diaphragms and preformed stiffeners brace adjacent panels and provide added stiffness for even more shape control.

ASTM A974
Know that all our gabions and mattresses are manufactured to the ASTM A974 standard, which also establishes minimum requirements for preassembly of the baskets and mattresses for shipping. The wire mesh used is galvanized or PVC coated for applications where greater durability is desired.
