Producer Statement (PS1)
UNEX Extreme Barriers are specifically engineered to comply with the extremely heavy liveload classes "C1/C2", "D" or "C5" of the New Zealand Building Code legally required for public and crowded areas. The Framed Baluster style has gaps between each baluster to offer a foot rest when leaning against the top rails. The Framed Glass style's thicker glass panels allow larger crowds to continue to watch the game or the view from above. Examples of the perfect use for this style of balustrade is in:
Scope of use
