Deck plank

A deck plank comprising:

• a top surface having a first edge portion and a second edge portion;
• a tongue attached to the first edge portion, the tongue having a first limb and a second limb defining a gap therebetween, the tongue further having an angled portion of a first angle;
• a groove attached to the second edge portion, the groove having an angled portion of a second angle, the tongue being adapted to fit with a groove of an adjacent plank;
• and
• at least two support legs extending from the top surface forming at least one open area beneath the top surface;
• wherein the first angle is sufficiently different from the second angle so that a space is maintained between the first angle and the second angle when the tongue is fit with the groove of the adjacent plank.

A deck comprising:

• a support;
• and
• at least a first and a second deck plank attached to the support, each of the deck planks comprising:
• a top surface having a first edge portion, a second edge portion, and an open area beneath the top surface;
• a tongue attached to the first edge portion and extending in a plane below the top surface, the tongue having a first limb and a second limb defining a gap therebetween, the tongue further having an angled portion of a first angle;
• and
• a groove attached to the second edge portion and extending in a plane below the top surface, the groove having an angled portion of a second angle, the tongue of the first deck plank positioned in the groove of the second deck plank;
• wherein the first angle is sufficiently different from the second angle so that a space is maintained between the first angle and the second angle.

A method of making a deck comprising:

• providing a support structure;
• providing a first and a second deck plank, each including a top surface having a first edge portion, a second edge portion, and an open area beneath the top surface, a tongue being attached to the first edge portion, the tongue having a first limb and a second limb defining a gap therebetween, the tongue further having an angled portion of a first angle, a groove being attached to the second edge portion, the groove having an angled portion of a second angle, the tongue being adapted to fit with a groove of an adjacent plank;
• attaching the first deck plank to the support structure;
• and
• attaching the second deck plank to the support structure adjacent the first deck plank;
• wherein the tongue of the first deck plank is adjacent to the groove of the second deck plank, and the first angle is sufficiently different from the second angle so that a space is maintained between the first angle and the second angle.
