Wall panel

Wall panel structure for outside use on buildings comprising:

• a plurality of elongated panel units of sheet material each having substantially parallel ends lengthwise thereof;
• a first leg having a cleft portion thereon;
• a first web attached to said first leg;
• a hairpin portion attaching said first web to one end of a first panel unit;
• an angled leg attached to a second web with the entire leg being at an obtuse angle of 112.degree. with respect to the second web;
• said second web being attached by an offset section having a void space to another end of said panel unit;
• said second web being shorter than said first web;
• whereupon upon assembly of a second panel unit with said first panel unit, the aforesaid hairpin portion of said first panel unit is received within the void space of the offset section of the second panel unit;
• said angled leg having a lip at the free edge thereof for snap engagement with the cleft portion of an adjacent panel unit;
• the lip of the angled leg of the second panel unit engaging the cleft portion of the first leg of said first panel unit for maintaining the assembled relationship of the first and second panel units;
• and
• said second web attached by said offset section to another end of said panel unit being at 92.degree. with respect to the central portion of the panel unit so that when two panels are snapped together, a continuous pressure is exerted between the webs of the respective panel units.
