Where Granberg products are made
Pittsburg, California
Granberg’s facility at 1051 Los Medanos Street in Pittsburg is where its mills and rail systems are built and shipped. The Alaskan MKIV is described by the company as tubular aircraft aluminum extrusion with zinc-plated steel parts — “high-quality U.S. made aircraft aluminum and steel” — and orders ship from that California facility.
Granberg’s own manufactured lines carry the origin claim explicitly: both the Alaskan MKIV mill and the EZ-Rail guide systems are labelled MADE IN THE USA on their product pages, and the company states its products are “American made and assembled.” Two honest qualifications belong here. The Precision Grinder sharpener page carries no origin statement, so it is not claimed. And Granberg also retails third-party forestry brands — LogOX tools, GB bars, safety gear — which are not Granberg-manufactured and are not covered by the claim.
The story
In 1954 Elof Granberg founded the company that still bears his name. He was an inventor by instinct: in 1957 he patented the File-N-Joint, a chainsaw filing guide that let a sawyer sharpen a chain accurately in the field rather than by eye.
The product that made the company’s name arrived in the 1960s, when Granberg took on the Alaskan mill — a bar-mounted frame that turns an ordinary chainsaw into a portable sawmill. It let one person convert a felled log into dimensional lumber where it lay, without a truck, a mill, or a road.
That idea has not needed reinventing. The Alaskan is now in its MKIV generation, joined by the EZ-Rail first-cut systems, winches, ripping chain and sharpeners, but the premise is unchanged: the mill goes to the log.
The company remains family-owned. Elof’s descendants still manage it, with Erik Granberg as president — a continuity now past the seventy-year mark.
Why they matter
Portable milling is a category where imported knock-offs of the Alaskan design are widely available and considerably cheaper. Granberg has kept building the original in California and marking it as US-made, which makes it one of the few places a sawyer can buy the genuine article and know where it came from.
The products also serve a distinctly American use case — salvaging urban windfall, milling on remote property, working timber that would otherwise be firewood. They are tools for getting value out of wood that a commercial mill will never see.
And the material chain is domestic where it counts: US-made aircraft-grade aluminum extrusion and zinc-plated steel, fabricated and assembled in Pittsburg rather than sourced abroad and badged here.

Frequently asked questions
Where are Granberg chainsaw mills made?
Granberg manufactures at its facility in Pittsburg, California, and ships orders from there. The Alaskan MKIV mill and EZ-Rail systems are marked MADE IN THE USA on their product pages.
How old is Granberg?
The company was founded in 1954 by Elof Granberg and describes itself as “Crafting Excellence Since 1954.” Its File-N-Joint sharpening guide was invented in 1957.
What is the Alaskan mill?
It is a portable chainsaw mill — a frame that clamps to a chainsaw bar so the saw can rip a felled log into boards on site. Granberg popularised the design and still builds it, now in its MKIV generation.
Is everything Granberg sells made in the USA?
No, and the company does not claim so. Granberg’s own mills and rail systems are US-made and labelled as such, but it also retails third-party forestry brands such as LogOX and GB bars, which are not Granberg-manufactured.
