Q. What is the most weight you can put in one of your cases?
A. Impact’s cases have been designed and manufactured for payloads in excess of 1000 lbs.

Q. Can your Standard cases be used outdoors?
A. The answer is Yes and No. Impact’s Quick Ship cases can be used outside for short periods
of time and short duration rain showers won’t affect them or what’s inside. However, if the
cases are meant to be outside for weeks, months, or year round, then we strongly recommend you consider one of our Military Cases. Impact’s Military Cases and containers are
airtight / watertight and have stainless steel hardware.

Q. Can you anodize your cases instead of powder coating them?
A. We prefer not to anodize our cases. Impact’s Quick Ship cases are manufactured using aluminum pop rivets with steel mandrels. The anodizing process disintegrates steel and will reduce the strength of these rivets. Anodizing does yield a protective layer (against surface oxidation), it is also very prone to scratching. Powder coating yields a tougher, more durable finish than anodizing.

Q. Is embossed / textured aluminum better than plain?
A. Embossed and textured metals are used extensively in architectural applications due to their aesthetics. Embossing (or “rigidizing”) sheet material will yield a moderate increase in flexural strength over plain material. The improved flexural strength of an embossed sheet is determined by it’s emboss pattern and depth. Sheet material with a deep, large diamond emboss pattern (such as found in industrial tread plate) will yield perhaps a 15 - 20% increase in flexural strength (over plain material of the same gauge) whereas a shallow, small oval emboss pattern would probably yield an increase in flexural strength of only 3 - 5% at best. The vast majority of embossed aluminum cases are manufactured from the shallow, small oval emboss pattern. Certain emboss patterns are better at hiding scratches - but only with unfinished aluminum or clear anodized aluminum finishes. Embossed aluminum which has been painted or colour anodized will accentuate scratches because the raised (embossed) surfaces are more exposed. You end up with patterned abrasion marks.

Q. You claim that your square tubular valance better than your competitors. Why?
A. Impact’s square tubular valance system is better than our competitors’ valance because:
Our competitors use open profile valance extrusions (typically in the shape of a "U" or "L"). Impact'svalance extrusion is a closed profile, square tubular design. The closed profile, square tubular design offers substantially superior flexural strength (resistance to bending) than the open profile design because there are two brace sections (running perpendicular to the case wall) instead of one. Our competitors miter cut their valance extrusion – the end result is a discontinuous valance with gaps in the corners. Thus, their valance is weak in the corners - where strength is needed the most. If a competitor’s case impacts along the corner edge, that gap (in the corner) tends to split open. Impact’s square tubular valance system incorporates high strength, investment cast corner lugs (patents pending) which interlock with the extrusion to yield a continuous valance and NO gaps. Our competitors’ valance extrusions use the simple “tongue and groove” design – with the base extrusion having the tongue profile and the lid extrusion with the groove. Impact’s square tubular valance incorporates the tongue and groove profiles in both the upper and lower extrusions – a design so strong that Impact’s square tubular valance has the greatest resistance to lid – base shearing forces in the industry.

Q. Can your cases have panel, panel frames or connector cutouts in the case shell?
A. Absolutely. In fact, our greatest strength is the complete customization of a case. Impact designs the case using parasolid modeling software and incorporates all “custom” aspects into that design. The case is then manufactured to that “custom” specification using CNC machines to ensure precise and repeatable geometry. This is a far cry from our competitors’ ad hoc approach to customizing cases – typically involves modifying a ready made case using hand tools.

Q. Can you manufacture cases or containers to meet specific shock or vibration requirements?
A. Yes. We will need to know the threshold parameters you require - i.e. what is the required peak deceleration (in g's) and from what drop height. For military and aerospace requirements, drop and vibration testing (if required) is done at an accredited independent laboratory.
