40 Foot Piling | Class B | .60 CCA Treated | Southern Yellow Pine

Product Overview

This is a 40-foot Class B wood piling made from Southern Yellow Pine, treated with CCA at a retention level of .60 pounds per cubic foot. The piling is grown, debarked, and treated in the United States and manufactured to ASTM D25 standards.

Class B pilings are the second-largest classification in the ASTM grading system, providing substantial structural capacity for foundation and marine applications. This piling weighs between 1,430 and 1,690 pounds depending on moisture content and density variation within the species.

The standard .60 CCA treatment provides protection against decay and biological degradation. Higher retention levels are available at .80, 1.0, 1.5, and 2.5 pounds per cubic foot for applications requiring increased chemical retention.

Where This Product Fits Best

A 40-foot Class B piling is appropriate for foundation work, dock construction, bulkhead systems, and structural support applications where moderate to heavy load capacity is required at depths up to 40 feet. The Class B designation positions this piling for projects that need more capacity than Class C but do not require the larger diameters of Class A.

Southern Yellow Pine is a common species for structural piling work due to its density, strength characteristics, and treatability. The .60 CCA retention level is a standard treatment for ground contact and freshwater applications. Saltwater or brackish water installations typically require higher retention levels.

Performance and Functional Considerations

The minimum tip circumference is 22 inches, with a minimum tip diameter of 7 inches. At 3 feet from the butt, the minimum circumference is 37 inches with a minimum diameter of 12 inches. These dimensions meet ASTM D25 requirements for Class B pilings at this length.

The taper from butt to tip affects driving characteristics and bearing capacity. A 40-foot piling with these dimensions will displace soil progressively as it is driven, which influences both installation effort and final load capacity in friction-bearing applications.

CCA treatment penetrates the outer sapwood to protect against fungal decay, termites, and marine borers. The .60 retention level is treated to American Wood Preservers Association standards. For severe exposure conditions, the optional higher retention levels provide increased chemical loading in the treated zone.

Installation and Long-Term Use

Handling a piling in this weight range requires appropriate rigging and lifting equipment. At 1,430 to 1,690 pounds, a crane or excavator with adequate capacity is necessary for unloading, positioning, and setting.

Pilings are typically driven using impact hammers or vibratory drivers. Soil conditions, required embedment depth, and bearing requirements will determine the driving method and equipment. The tip diameter and taper influence how the piling responds during driving.

Once installed, CCA-treated Southern Yellow Pine requires no routine chemical retreatment under normal conditions. Inspection for mechanical damage, checking, or exposure of untreated wood at cut ends is standard practice for long-term structural integrity.

How This Fixture Is Commonly Used

A Class B piling at 40 feet serves applications where the structural load or embedment depth exceeds what smaller piling classes can handle. You would typically use this where soil conditions require deeper embedment to reach bearing capacity, or where the supported structure demands the load rating that a Class B provides.

The treatment level you select depends on the exposure environment. The standard .60 retention works for most ground contact and freshwater situations. If you are installing in saltwater, brackish water, or in areas with heavy marine borer activity, you would move to one of the higher retention options to extend service life.

When you receive pilings, verify the circumference and diameter measurements at the tip and butt locations match the minimums for Class B. This confirms the piling meets the grade and will perform as expected under design loads.

Safety, Certifications, and Warranty

This piling is manufactured to ASTM D25 standards and treated to American Wood Preservers Association standards. These standards govern dimensional tolerances, species requirements, and treatment specifications for round timber pilings.

CCA-treated wood requires standard handling precautions. Wear gloves when handling, avoid prolonged skin contact, and do not burn treated wood. Sawdust and debris from cutting should be collected and disposed of properly.

This product carries a 1-year warranty.
