1

Pick Your Size

Browse carports from 10x20 to 20x40 FT and select the coverage area that fits your driveway or property.

2

Shelters Designed for Real Properties

FILLOSLOV started with a straightforward idea: rural homeowners and property managers deserve vehicle shelters that hold up through Montana winters, Texas summers, and everything between. Our team sources galvanized steel from certified mills and engineers each frame for wind loads, snow loads, and long-term corrosion resistance.

Every carport kit leaves our facility with pre-drilled holes, labeled components, and a step-by-step assembly guide. Our greenhouse line extends the same durability-first approach to backyard gardeners who want to grow vegetables, flowers, and seedlings year-round in a polycarbonate-paneled structure.

Customer Reviews

Real feedback from verified buyers who assembled and use FILLOSLOV shelters on their properties.

★★★★★

Chose this 10x20 metal carport for my new home's driveway, and the size fits perfectly. The galvanized steel frame feels solid, and the vertical roof design handles drainage well. Shelters my SUV and a canoe without taking up too much yard space. The 10x20 coverage works for standard vehicles and a small boat side by side.

I needed a carport that could fit my full-size pickup truck with room for a workbench. This 12x20 oversized model cleared the roof of my high-cab truck with no issues. The width lets me keep tools on the side. Rainy season came and went with zero pooling on the vertical roof. Worth the investment for a larger-than-standard shelter.

Both family cars fit under the 20x20 with room to spare. The galvanized construction gives me confidence this structure will last. Assembly took two adults about a weekend. Every bolt tightened cleanly and the frame felt rock-solid by the time we finished. Works like an open garage with excellent overhead protection for two vehicles.

Instructions could use more detail, but once you figure out the assembly sequence, the build goes smoothly. I completed mine solo in about a day and a half. Roof panels come in two lengths for different sections. The long tin box holds the instruction sheet at the bottom, so check there first. Solid structure once everything is bolted together.

We joined two 20x20 carports together to cover a 1966 Ford Galaxie hot rod, a '94 Camaro, a 2006 Subaru Baja, and all our lawn equipment. Still have room to fire up the grill and make pizzas underneath when it snows. The combined setup provides a snow-proof cover that handles Montana winters without bowing.

★★★★☆

Goes together nicely with accurate fit on all the connectors. The galvanized frame resists the coastal humidity we deal with in the summer months. My boat sits dry underneath during storm season. I would recommend having a second person for the roof panel installation since the sheets can catch wind if you're working alone.

Expert Recommendation

Structural engineer Robert Callahan
"Galvanized steel adds 15 to 20 years of corrosion resistance compared to bare or powder-coated frames. The vertical roof geometry on the FILLOSLOV line eliminates standing water, which is the single biggest cause of premature rust in residential carport structures. For homeowners in snow-heavy regions, the reinforced truss design distributes load across the frame instead of concentrating it at the ridge."

Frequently Asked Questions

Answers to common questions about FILLOSLOV carports, greenhouses, and assembly.

FILLOSLOV carports come in 10x20, 12x20, 20x20, 20x30, and 20x40 FT configurations. The 10x20 covers one to two standard vehicles. The 12x20 accommodates full-size trucks and boats. The 20x20 and larger sizes shelter multiple vehicles, RVs, or agricultural equipment.

Most 10x20 and 12x20 models take two adults a weekend (roughly 8 to 12 hours). Larger 20x20+ configurations may take an additional day. All kits ship with pre-cut parts, hardware, and an anchor kit. No welding or specialized tools required.

Galvanization bonds a zinc layer to the steel at the molecular level, creating a barrier that prevents rust even when scratched. Powder coating is a surface treatment that chips and peels over time, exposing bare metal to moisture. Galvanized frames outlast powder-coated alternatives by 10 to 15 years in outdoor environments.

The vertical roof design sheds snow rather than accumulating it. The reinforced truss structure distributes load evenly across the frame. In regions with sustained heavy snowfall, FILLOSLOV recommends clearing accumulated snow from the roof after major storms to maintain structural integrity.

The 12x20 model is rated for winds up to 100 MPH when properly anchored. All kits include a ground anchor system. For areas with extreme wind exposure, FILLOSLOV recommends adding concrete footings to the anchor points.

No concrete foundation is required. The included anchor kit secures the frame to packed earth, gravel, or asphalt. For maximum stability in soft soil, pour small concrete pads at each anchor point. The carport functions on flat, level ground of any surface type.

Vertical roof panels run from ridge to eave in a straight downward angle, channeling rain and snowmelt off the sides of the structure. Rounded or flat roof designs trap water in low spots, leading to pooling, leaks, and accelerated rust. The vertical design eliminates these problems.

Yes. The open-sided design accommodates workbenches, grills, outdoor furniture, and equipment. Several customers use the larger models as covered outdoor spaces for events, vehicle maintenance, and seasonal storage.

FILLOSLOV offers an 8x10 FT walk-in greenhouse with a rust-resistant aluminum frame and twin-wall polycarbonate panels. Features include an adjustable roof vent, integrated gutter system, and lockable door. The polycarbonate panels block harmful UV rays while diffusing light for healthy plant growth through all seasons.

Yes. FILLOSLOV sells replacement panels and structural accessories for both 12x20 and 20x20 carport models. These galvanized steel components match factory specifications for seamless compatibility with your existing structure.

Reach the FILLOSLOV support team through the contact page on this website or by calling (406) 555-0183 during business hours. Response time averages 24 hours for email inquiries. The team assists with assembly questions, replacement parts, and customization requests.

Technically possible for smaller models. One customer completed a 10x20 solo in about a day and a half. FILLOSLOV recommends two people for safety and efficiency, especially during roof panel installation where sheets can catch wind.
