Galvanised Steel Grain Silos

Galvanised steel has been the structural standard for industrial grain storage for decades, and the reasons haven’t changed. Corrosion resistance, structural strength, and the ability to handle the heavy loads of stored grain in a UK climate are all qualities the material delivers consistently. A galvanised steel grain silo gives you a sealed, durable, weather-tight storage vessel that protects grain quality through long-term storage cycles. Franklin Hodge manufactures galvanised steel grain silos as part of the Brice-Baker range, with G600 coating, hot-dipped heavier components, and capacities scaled for UK farm and grain handling operations.

Why Galvanised Steel Is the Standard for Grain Silo Construction

The choice of material for a grain silo isn’t arbitrary. Galvanised steel sets the standard because it solves the specific problems grain storage creates: corrosion exposure from atmospheric moisture, the weight and outward pressure of bulk stored grain, and the long service life needed to justify the capital investment in storage infrastructure. 

Hot-dip galvanising bonds a zinc coating to the steel surface, creating a protective layer that doesn’t peel, flake, or wear off in the way painted finishes do. For a silo that lives outdoors for decades, that distinction is the difference between a siklo that needs recoating every few years and one that simply works.

G600 Galvanised Steel: The Brice-Baker Specification

Our Brice-Baker silos are manufactured from G600 galvanised steel, with wall thicknesses up to 3mm and heavier structural components hot-dipped for additional protection. The G600 designation refers to the zinc coating weight applied to the steel, and it’s the specification we’ve settled on after decades of UK manufacturing experience for the balance it strikes between corrosion resistance, structural integrity, and operational economics. 

The wall sheets use a shallow profile design with external stiffener columns. That combination delivers two practical benefits: cleaner discharge with minimal material hang-up on internal surfaces, and stronger structural performance under load. All silos are manufactured in compliance with BS EN 1090-1:2009+A1:2011 standards for steel structures.

Flat Bottom and Hopper Bottom Galvanised Steel Grain Silos 

Galvanised steel grain silos from Franklin Hodge are available in both flat bottom and hopper bottom configurations to suit different grain storage operations. Flat bottom silos suit larger-capacity, single-crop bulk storage, with diameters ranging from 3 to 25 metres. Hopper bottom silos suit operations that prioritise gravity discharge, batch separation, or storing multiple grain types, available in 3 to 12 metre diameters. 

Both configurations use the same G600 galvanised steel construction. The difference sits at the base of the silo and in how the operation handles discharge, not in the durability of the storage vessel itself.

Capacities and Dimensions of Brice-Baker Galvanised Steel Silos

The galvanised steel grain silo range covers working capacities up to 11,888m³, with the diameters above and heights tailored to your site footprint and storage volume targets. Optional features include access ladders, platforms, gantry systems, and integrated handling equipment such as dryers and conveyors. 

Spec sheets covering the full range are available in our downloads section to support the specification stage, and our engineering team will model the right configuration against your site dimensions and capacity requirements.

Inspection and Refurbishment of Galvanised Steel Grain Silos

A galvanised steel grain silo correctly specified at the start will deliver decades of service, but a structured inspection and maintenance programme is what protects that investment over time. Our silos inspection service uses drone technology to assess silo condition externally without putting engineers on the silo wall, with high-resolution imagery flagging any corrosion, panel wear, or structural issues early. 

Where inspection findings require action, our silos refurbishment team handles structural repairs, panel replacement, and full restoration. The galvanised steel construction is what makes refurbishment a viable alternative to full replacement on most installations.

Frequently Asked Questions 

What grade of galvanised steel are Brice-Baker grain silos made from? 

Brice-Baker silos are manufactured from G600 galvanised steel with wall thicknesses up to 3mm, and heavier structural components are hot-dipped for added corrosion resistance. 

Are galvanised steel grain silos suitable for UK weather conditions?  

Yes, the G600 galvanised coating delivers excellent corrosion resistance across UK climate conditions, making the silos suitable for outdoor installation on any farm site. 

What capacities are available across the galvanised steel grain silo range? 

Brice-Baker galvanised steel grain silos cover working volumes up to 11,888m³ across both flat bottom and hopper bottom configurations. 

Do you supply both flat bottom and hopper bottom galvanised steel silos? 

Yes, our range includes flat bottom silos from 3 to 25 metres diameter and hopper bottom silos from 3 to 12 metres diameter. 

How long does a galvanised steel grain silo last? 

Correctly maintained, a galvanised steel grain silo will deliver decades of operational life, supported by our inspection and refurbishment services where extension is needed.
