Steel structural plate is used when any type of manufactured pipe would be too large for conventional shipment methods.  Structures of larger size may be required for bridge or hydraulic structures with spans exceeding 12 feet, when deep earth covers (depths exceeding 200 feet) or heavy vehicles or equipment result in large loads being applied to the assembled pipe.  These structures are assembled in the field by bolting together fabricated plates that have holes punched around the periphery of the plate.  The plates are formed using a very strong 6” x 2” corrugation, are made with heavier plate than that used in fabricated corrugated steel pipe and are curved for added stiffness.  All these features result in corrugated structures capable of supporting heavy loads and spanning greater distances.

Structural plate is designed and fabricated into six shapes that vary from round pipe up to 26-foot diameter, to low profile box culverts that have spans in excess of 20 feet, with correspondingly low head room requirements.  Shapes such as the low profile box culvert, the pipe-arch or the arch allow a greater volume of flow through the pipe when head room restrictions limit the height (rise) of the structure.  If height limitations do not exist, round pipe should be used since it is the easiest shape to fabricate and install and thus the most economical.

This product is very versatile and can be used for a large variety of applications other that the conventional uses such as culverts, storm sewers and small bridge structures.  The underpass shape is particularly adaptable to passages for vehicles, golf carts, livestock or pedestrians if the site allows slightly more headroom.  With more attention being devoted to environmental concerns, several of the six shapes are useful as wildlife passages under roadways.  Steel structural plate shapes are also useful in many industrial applications such as conveyor tunnels, mine entryways, utility tunnels, ski tunnels, underground storage, equipment enclosures or vertical shafts for a number of applications.    

At many potential sites for hydraulic conveyance structures or bridge structures, construction specifications limit or prohibit disturbance of the natural streambed.  The arch or low profile box culvert shapes can be installed without inverts, thus eliminating any disturbance to the streambed during construction, and maintains the natural environment after installation.  These two structures are also useful for crossing wetlands.  The variety of structural steel plate shapes and Lane’s fabrication capabilities allow this product to be used in an extremely large variety of  applications.  Your imagination is the only limit to potential applications.

DEEP CORRUGATION STRUCTURAL PLATE
Lane distributes steel structural plate products that have significantly greater strength than the standard 6" x 2" structural plate corrugation. These products are available in several shapes and because of the stronger corrugation can span up to 70 feet.  For more information, please contact Lane Enterprises, Inc.
