In addition to cardboard mortar tubes, Skylighter carries mortar tubes made from high density polyethylene (HDPE) and fiberglass.

HDPE is considered the safest material to use for making fireworks mortars. It is tough, can take a lot of abuse and firings, and can last a lifetime. It can get wet with no problems. And if a fireworks shell explodes in an HDPE mortar, there are few, if any, sharp-edged pieces of shrapnel to injure people. That's because HDPE doesn't shatter--it shreds and tears. Each mortar tube is plugged with a 1-5/8 inch thick wooden plug.

Our fireworks mortars in racks are professionally made wooden racks containing 6 black HDPE mortar tubes, each plugged and glued with a wooden plug. Best of all, they are arranged in a "fan" shape. That means that when you fire your festival balls or artillery shells, they will spread all over the sky, even though they are fired from one place on the field.

Fiberglass is cheaper than HDPE. Our fiberglass mortars are made in China and are color-coded to make it easier to keep track of them when loading fireworks. If a shell detonates in a fiberglass mortar, the tube tends to shred and tear, and is much safer than metal tubes or PVC (which should never be used in fireworks, because it can produce dangerous shrapnel).
