Pin Lok Scaffold Plank has the following common-sense qualities that explain the superior reserve strength to support sudden unexpected loads:

1) Every piece of woodhas its own level of shock absorbtion. The multiple pieces of wood used in a Pin-Lok plank are aligned to resist a greater cumulative shock.

2) Each member has grain aligned in different directions, helping to disperse the load.

3) With multiple pieces the load is distributed evenly across all members, with the stronger pieces supporting the weaker. This butcher-block effect adds approximately 20% more strength to the entire plank.

4) Steel twist-lok rods bind the plank members into a single strong unit.The twist-lok rods in the plank are positioned so that any damage or defect is never more than 12 inches away from a rod. Cracks cannot travel past a twist-lok rod.

Developed after years of study and testing, Indian Mill's Pin-Lok
Scaffold Planking was designed to be the strongest, safest, most durable
plank on the market.
In our patented Pin-Lok process, multiple structural members of Dense Select Grade Southern Yellow Pine or Douglas Fir lumber are milled to size. The center strip
is sealed to keep out moisture and job-site chemicals and aligned for
the greatest possible strength from the material. Heat-treated twist
steel pins are then inserted every 22 inches along the plank's length to
bond the three pieces into a single solid unit. The resulting planking is stronger, more resistant to moisture and chemicals, and safer in overload than standard DI-65 or laminated scaffold planking.

In tests conducted both at our facilities and at Purdue University, the resulting plank resists point, center and shock loads which destroyed standard DI65 and
high-grade laminated wood planking.

Built In Safety:

In a situation where the plank is damaged or overloaded, the center section of the plank is designed to break first, giving an audible and visible warning. At that point the plank is damaged but complete failure has not occurred and workers have time to safely exit the scaffold. Other types of planks lack this feature and can fail catastrophically with little or no visible warning causing serious fall hazards for workers.

Due to the insertion of the steel twisk-lok pins over the entire length
of the plank they are extremely resistant to warping and cupping compared to standard wood planking. They are also quick to dry due to the sealed center section of
the plank. We offer optional custom embossing and custom branding of the
planks so that you can keep your inventory sorted at the job site, and we can manufacture the planking to standard or custom lengths to meet your needs. Indian Mill's Pin-Lok planking is competitively priced . Quantity pricing is available.

The Pin-Lok plank shown in this picture was broken during testing. The plank failed at over 2900 pounds - higher than either a laminated or DI-65 board - and still has enough reserve strength to support 4 grown men.

Planking life is greatly affected by storage conditions. Do you know how to properly care for your planks to get the best return on your investment?
