We specialize in the manufacture of laminated, three-ply, bolted hardwood, mats. We manufacture both squared and fingered and pocketed mats. Our mats are manufactured from rough cut, full dimension, nominal size 2' x 8' hardwood lumber consisting of minimum 90% Oak with up to 10% class 5 dense hardwoods with a specific gravity equivalent to or in excess of Oak. We utilize 3/8" by 6" steel carriage bolts for fasteners using field tested proven bolt patterns which are designed to help prevent diamonding during application and handling. Bolts are torqued, recessed and countersunk in order to facilitate sliding during field installation. Bolts are rounded on top of mats to prevent exposure to any sharp edges. Standard mats are made with three 12" fingers and three corresponding 12" pockets to hold mats in place. All lumber is precision end trimmed on our K-20 Newman and end waxed and sealed prior to manufacture in our steel framed assembly stations. This type of mat is best suited for "hands-on" manufacturing for better placement of bolt patterns which must be adapted to variance in individual board sizes. We are currently making the following "stocking" sizes and types of three-ply mats:

Our "Standard" mat: (the most widely used industry mat)

Sizes: Available in 6" x 8' x 8', 12', 14', 16' ( most common size is 6" x 8' x 14') Species: 90% minimum Oak. Maximum 10% Class 5 hardwoods (i.e.: Hickory, Beech, Gum) specific gravity of Oak or better. Bolts: 3/8" x 6" Steel carriage bolts. Standard 148 pc bolt pattern for 14" mats. Custom bolt patterns also available. Board: Eleven top boards; eighteen center boards; eleven bottom boards. Composition: Available in either squared or fingered and pocketed. Trans: Available for truck or rail delivery.

Our "Premium" mat:

Sizes: Available in 6" x 8' x 14'. Species: 90% minimum Oak, maximum 10% class 5. Bolts: 3/8" x 6" steel carriage bolts. Composition: 160 pc bolt pattern; eleven top boards; 20 center boards (basically a solid center); eleven bottom boards. Available in either squared or fingered and pocketed. Trans: Available for truck or rail delivery.

Crane Mats:

Sizes: Standard size is 8" x 4' x 18' (other sizes available for special order). Species: timbers are 100% Oak. Fastening: 1" x 4' through bolts with offset exposed bolt for pick-up and handling. Trans: Available for truck or rail delivery.

Advantages of using NorWest bolted mats:

• Exclusive "Field tested and proven" bolt patterns.

• Lumber is P.E.T. and end coated & waxed to cut down on water absorption and end splits.

• Lumber is air-dried , prior to assembly, to help prevent pop-ups and loosening of bolts due to lumber shrinkage.

• Cross-laminated design creates unusual strength which ordinarily could only be achieved by much larger mats.

• Mats are stronger relative to weight than any other wood mats: they are much more mobile than larger, steel framed mats, and far superior to softwood mats in strength and durability.

• Mats are re-useable and easily repaired. Damaged boards can be easily replaced and simply re-bolted.

• Under ordinary use, our mats will last for years.

Typical Uses:

• Access roads and drilling pads in areas of unstable soils, tundra, muskeg, muddy or swampy areas.

• Camp sites or storage sites for remote storage or mobilization for equipment.

• Roads and turnarounds in environmentally sensitive areas.

• Logging projects for log pads and roads.

• Pipeline construction and storage.

• Winter camps and storage pads.
