Carport Central 12' x 21' Metal Carport

    • Fast shipping
    • Arrived as described

    • Missing pieces on one order
    • Instructions described as poor
    • One buyer felt the build was light duty and cheaply made

    Questions and answers

    Which is better for snow?
    The EROMMY publishes a 30-35 PSF snow load; the Carport Central publishes none. A rigid steel roof handles drifting snow better, but without a rating, clear the Carport Central roof after heavy storms.
    Which lasts longer?
    The Carport Central's galvanized steel roof should outlast the EROMMY's 220gsm PE tarp, which is the wear item. The EROMMY frame is galvanized and powder coated, so rust is less of a concern than tarp replacement.
    Which is better for an RV or boat?
    The EROMMY, at 20 by 20 feet with 280 square feet and a 12.1-foot peak height. The Carport Central's 12-foot width and 21-foot length are tight for larger RVs.
    Is the EROMMY worth it over the Carport Central?
    Only if you need the extra square footage, doors and windows, or the published wind and snow ratings. If a hard roof over one vehicle is enough, the Carport Central is the simpler structure.
    Can the EROMMY handle 60 mph winds?
    EROMMY rates it at 60+ mph, but that assumes proper anchoring to soil, asphalt or concrete. Anchor it per the manual; an unanchored tarp shelter will fail well below that.
    How much assembly does each need?
    EROMMY quotes about 45 minutes with four people. Carport Central does not publish an assembly time, but steel-roof carports typically take two people several hours.
