30 Foot Piling | Class A | .60 CCA Treated | Southern Yellow Pine

Product Overview

This is a 30-foot Class A wood piling manufactured from Southern Yellow Pine. The piling is pressure treated with CCA (Chromated Copper Arsenate) at a retention level of .60 pounds per cubic foot. It is grown, debarked, and treated in the United States and manufactured to ASTM D25 standards.

Class A pilings are the largest diameter classification in the ASTM grading system. This piling has a minimum tip diameter of 9 inches and a minimum diameter of 14 inches measured 3 feet from the butt end. Corresponding circumference minimums are 28 inches at the tip and 44 inches at 3 feet from the butt. Weight ranges from 1,000 to 1,200 pounds.

Treatment is performed to current American Wood Preservers Association standards. Higher CCA retention levels are available as optional treatments at .80, 1.0, 1.5, and 2.5 pounds per cubic foot for applications requiring increased protection.

Where This Product Fits Best

Class A pilings at 30 feet are used where structural load demands require the largest available cross-section in the ASTM D25 classification system. The 14-inch minimum butt diameter and corresponding taper provide load-bearing capacity suited for heavy foundation and marine structural work.

The standard .60 CCA treatment level is appropriate for ground contact and freshwater exposure. For saltwater, brackish water, or high-decay-hazard environments, optional treatment levels up to 2.5 pounds per cubic foot are available and may be required depending on site conditions.

Performance and Functional Considerations

Southern Yellow Pine accepts pressure treatment effectively due to its cellular structure, which allows deep penetration of preservative chemicals. CCA treatment protects against fungal decay, termites, and other wood-destroying organisms in ground contact and water immersion applications.

The weight range of 1,000 to 1,200 pounds should be factored into equipment planning for transport, handling, and driving. Pilings at the upper end of this weight range will require lifting and driving equipment rated accordingly.

ASTM D25 manufacturing standards govern dimensional tolerances, straightness, and knot limitations. These standards ensure consistency across pilings for load calculation and installation sequencing.

Installation and Long-Term Use

Driving equipment must be matched to the piling weight and Class A dimensions. The 9-inch minimum tip diameter affects driving resistance and penetration behavior depending on soil composition. Harder soils and higher blow counts should be anticipated compared to smaller-class pilings.

Field cuts expose untreated wood and require field treatment to maintain preservative protection at cut surfaces. This applies to both tip and butt cuts made during installation.

Long-term performance depends on matching the CCA retention level to the exposure environment. Standard .60 treatment is not intended for direct saltwater immersion in marine borers zones. Where higher hazard conditions exist, specifying an optional higher retention level at time of order is necessary.

How This Fixture Is Commonly Used

Pilings of this class and length are typically driven as foundation elements for docks, piers, bulkheads, and building foundations in coastal and waterfront construction. The 30-foot length accommodates embedment depths and above-grade heights common in these applications.

The Class A designation is selected when engineering calculations call for the highest load capacity available in the ASTM system for a given length. Where lighter loads allow, smaller class pilings at lower weight reduce handling and driving requirements.

Treatment level selection is based on the installation environment. Freshwater and ground contact applications commonly use .60 retention. Marine and high-hazard applications require project-specific evaluation to determine if higher retention is needed.

Safety, Certifications, and Warranty

This piling is manufactured to ASTM D25 standards and treated to American Wood Preservers Association standards. These standards govern physical dimensions, allowable defects, and preservative retention verification.

CCA-treated wood requires handling precautions. Sawdust and debris should not be burned, and cuts should be made in well-ventilated areas. Treated wood should not be used where it may come into direct contact with drinking water supplies.

This product carries a 1-year warranty.

Frequently Asked Questions

What is the difference between CCA retention levels?
The .60 standard treatment is measured in pounds of preservative per cubic foot of wood. Higher retention levels (.80, 1.0, 1.5, 2.5) increase the concentration of preservative in the wood for more aggressive decay or marine borer environments.

What are the minimum dimensions for this piling?
Minimum tip diameter is 9 inches. Minimum diameter at 3 feet from the butt is 14 inches. These are ASTM D25 minimums for Class A at this length.

How much does this piling weigh?
Weight ranges from 1,000 to 1,200 pounds depending on moisture content and density variation within the Southern Yellow Pine species.

What is the warranty coverage?
This piling is covered by a 1-year warranty.

Is this piling suitable for saltwater use?
The standard .60 CCA retention is intended for ground contact and freshwater. Saltwater and marine borer exposure typically require higher retention levels, which are available as optional treatments.
