6061-T4 AND -T6 TREAD SHEET
TECHNICAL DATA
C102 (Diamond) Pattern
Strength, skid resistance, and durability are the major attributes of Alcoa’s 6061-T6 tread sheet and plate. A wide range
of sheet and plate thicknesses are offered as standard products and are available in a variety of widths and lengths.
Strength — 6061 tread sheet and plate is heat treated and aged to the -T6 temper to provide the highest strength
standard tread product available. This property makes 6061 tread ideally suited for consideration in applications where
heaviest loading is involved.
Durability — Long-term performance in loading ramp, trench cover, dock board, dock plate, flooring, stair tread, and
other similar applications has established 6061-T6 tread as a preferred product. High strength is combined with corrosion
resistance and light weight to highlight 6061 compatibility with many applications.
Skid Resistance — The raised diamond tread design provides improved footing where needed. Improved footing is
maintained due to high durability.
