Metal roofing has come a long way since its arrival on the construction scene in the 1820's. Invented in Britain by Henry Robinson Palmer, corrugated roofing sheets were originally made from wrought iron.

Even in its most primitive form, metal roofing was lighter, stronger, and lasted longer than most other. Introducing the Moffett. Graber Supply added this handy piece of equipment to our fleet in the fall of 2016. What is a Moffett? It's a truck-mounted forklift providing more productive and flexible delivery options for our customers.

The founder, Reuben Graber grew up around the pole barn industry. After finishing school, he worked for a pole barn construction company until he got married and started his own business in 1990. Reuben started selling garage doors from his home in Chester County, Pennsylvania. His business grew quickly, and he also started selling metal and screws.
R-Rib is a different look and is used more on commercial buildings, but can be used to create a distinct look on any building. All three metal options are beautiful and available in 22 colors with a 40-year limited warranty. Graber Buildings can be built with any color combination you choose for roofing, siding, wainscoting and trim.
Post frame buildings are an excellent choice for agricultural processing, animal facilities and equipment storage, or industrial manufacturing and warehousing. From storage, to herding and holding pens for animals, we'll design a building that will serve you for many years. Pole barns are a strong, durable and economical alternative to the more expensive steel building option, and are very easy to expand as your needs change and grow.
Graber pole frame buildings are a solid, attractive and economical solution for storing just about anything. Before you rent a storage unit, or buy a shed kit from a big box store, give us a call. Graber customers have used their storage structures to store antique cars, boats and tractors, RVs, or bulk materials such as hay, lumber, salt and concrete.
Let the Graber team help you design a custom post frame building that truly meets your purpose. We're here to listen, and provide a solution in the design of your structure. We've helped hundreds of clients create and build something that not only looks fantastic, but also stands the test of time. Multi-purpose and use buildings are not only economical, they are resourceful and responsible in preserving space on your property.

Graber was a pleasure to work with. They knew I was on a tight budget and they did not try to sell me anything I didn't need. The work crew came in and constructed the board and batten barn in less than three days. Several neighboring farms commented to me what a professional job was done. I believe this was the first barn they built in Delaware County, NY. I dealt with Mark and he was a gentleman during the entire process. I fully recommend them.

I cant say enough great things about my polebarn by Graber and the entire process. Mark was excellent with getting me started and walking me through the process and the workers busted their humps in extreme heat for a week. Delvin and Landon we professional and respectful while on site too. Im 100% satisfied with craftsmanship and quality of the garage. I want to thank everyone involved. Be safe.

A great customer experience from start to finish. We worked with Mark in the Sales Dept and he was a great advisor -- not pushy in any way. He took the time to explain different features and options available, as well as the benefits of each design feature. I had obtained quotes from several builders and Graber was significantly lower than the others. Upon completion of construction I received follow-up calls from Mark (in Sales) and the CEO (Mr. Graber) inquiring as to my satisfaction. Great product, great price, great customer service. Everything we wanted. Highly recommend Graber Buildings.

We hired Graber Supply to build our four-stall horse barn in PA and are very happy with the results. My experience with them throughout 2015-2016 was outstanding in a positive way!
I considered at least 5 different builders for our project, and ultimately chose Graber because of their pricing (far lower than Morton and similar big-name builders, only slightly higher than the local Amish folks), their experience and evidence of many prior satisfied clients, and their contact person (Lewis) who was accessible by email with quick response times and endless patience as we revised and adjusted our

The worst company I have ever dealt with in my professional building career. Too much to write about. If you want GREAT customer service and quality buildings look elsewhere. I'd give no stars if I was able to.

We are in the process of constructing a house based on a Graber barn. To make sure we met all the stringent building Codes for a residency plus make the barn a home, we also employed an architect. This required much coordination among the folks involved - the structural aspect, the barn design, and the architectural aspect. Our contact with Graber, Mr. Lewis Zook, has been awesome with whom to work on this project. There are always things that can go not as planned on any construction project. How issues are resolved is the key - Lewis has always been there for us and made things right in a very
