Pallet Wood Types Hardwood vs Softwood & How Species Affects Performance
Florida Pallet Supply • Updated 2026-03-30
Most buyers treat wood pallets as a commodity - a pallet is a pallet. But the lumber species used in construction significantly affects pallet weight, strength, nail retention, moisture resistance, and long-term durability. In Florida's high-humidity, high-heat environment, wood species choice matters more than in most states.
This guide explains the common pallet wood species, their performance characteristics, and why Florida's climate makes certain species preferable.

Pallet Lumber & Sawmill Operations
Stamped kiln-dried pallet lumber, bulk warehouse stock, dimensional yard inventory, raw softwood logs, and sawmill operations - the supply chain behind every custom and standard pallet we ship.

Southern yellow pine (SYP) is the dominant pallet wood species in Florida and the entire Southeast United States, due to its regional abundance, high resin content, and excellent strength-to-weight ratio. SYP is a dense softwood (heavier than most 'hardwoods' in practical terms) with tight grain and good nail holding. Its resin content provides natural moisture resistance - a significant advantage in Florida's humid climate. Most new GMA pallets manufactured in Florida use SYP.
Oak and Mixed Hardwoods
Oak, hickory, and mixed hardwoods produce the heaviest, most durable pallets. Hardwood pallets are preferred for very heavy loads (3,000+ lbs), repeated forklift impacts, and long-cycle applications where durability justifies the higher weight cost. A hardwood GMA pallet can weigh 50-60 lbs vs 35-45 lbs for SYP - this adds up when workers are manually positioning pallets or when calculating truck payload limits.
Recycled Mixed-Species Pallets
Most recycled pallets use mixed-species lumber boards from multiple repair cycles. A Grade A recycled pallet may have SYP stringers with oak or poplar deck boards. This is perfectly functional for standard applications, but the weight variation and inconsistent nail patterns require attention. For automated systems requiring precise dimensional consistency, new single-species pallets are preferable.
Florida Climate Considerations
Florida's year-round heat and humidity accelerate wood degradation, mold growth on stored pallets, and joint loosening from expansion/contraction cycles. To maximize pallet life in Florida: store pallets under cover or wrapped, avoid direct ground contact (use dunnage or pallet feet to allow air circulation), and prefer SYP over lower-density softwoods for exterior or humid environments. Kiln-dried lumber pallets resist moisture uptake better than green lumber pallets.
Frequently Asked Questions
Wood species is the primary variable. An oak-stringer pallet can weigh 55 lbs while a similar SYP pallet weighs 38 lbs. Worker safety, truck payload calculations, and handling equipment ratings are all affected by pallet weight.
No. ISPM-15 applies to all wood species equally. The treatment (heat to 56C core temperature for 30 minutes) is the same regardless of species.
Yes, from Florida Pallet Supply. We manufacture new pallets with specified lumber species on request. For recycled pallets, species cannot be guaranteed due to the nature of the repair supply chain.

The most common wood species used in pallet manufacturing in the United States are Southern Yellow Pine (SYP) and hardwoods including oak, maple, and ash. Southern Yellow Pine dominates pallet production in the Southeast because of its density, nail-holding strength, and suitability for ISPM-15 heat treatment. Hardwood pallets are heavier but structurally stronger and preferred for very heavy industrial loads and high-cycle racking in the Midwest. The wood species used in a pallet affects its weight, load capacity, heat treatment response, and longevity under repeated use.
