Three stars are generous. The quality of this product is low. Most of the grating is held on not by welds but by paint as the welds have melted through the 16ga wire. So the wire sticks up on the end and makes it next to impossible to slide things on it. More on the welds, as other reviews state they must be ground down in order for the holes to line up. Also there is sections that the weld has melted through the base metal leaving a hole instead of a weld. The paint will flake off during installation. It looks like it’s powder coated as it’s thick. As is the weld slag that wasn’t cleaned off before paint but the paint flakes off at the touch of other metal. The fasteners are not graded fasteners nor is the finishing quality decent. While you’re holding the grates in the air you’re arguing with the nut trying to get it on as the end of the bold is not chamfered so the threads are raw on the ends making it even more difficult to line up the nut. Also they only expect you to hold the weight on one fastener per leg, not being graded I’m sure the shear weight is not 400lbs as advertised. Another note on fasteners. I bought two of these grates. One package had three extra bolts and the other was lacking two. Proper installation of fasteners says to atleast put a washer on the head side of the bolt. Between both kits I might have received 9 flat washers. Who knows what they were supposed to be for as there were no instructions included. A quick search on the web provided instructions but they say to put together on the ground and flip it over and install to ceiling. Not sure who thought that was brilliant as the thing weighs over 100lbs and is 8 feet long. To do it like that you will need a fork lift or 3 people. Also if you plan to install on the ceiling you will need to buy lag bolts to your liking as the kit only comes with concrete anchors. Not sure who has a concrete ceiling but they won’t do you any good in wood rafters or metal rafters. Though they arrived a week before designated time the boxes were absolutely destroyed. The corners were completely ripped open. So what’s the good? Well it for sure holds 200 lbs. though it bends in the middle at that weight. They are mostly painted black so it looks pleasing until you get close and see the rust spots. And I received them within 5 days of ordering. So there are your three stars. Safe yourself 5 hours of installation time per grate (I was by my self) and spend the extra $30 and knock off the shipping and just get the husky grates. They are more sturdy and come with the proper fasteners and actual powder coating and rounded grates. Most of all they come with instructions a one man operation can handle.
