3 productsWhere our materials work
Industries we supply
Materials are selected by process and lining zone, not only by chemistry.
Iron and steelmaking
Refractories and consumables across the route from blast furnace to continuous casting, including hot-repair materials that keep vessels in service between relines.
View range →Iron ore pelletizing
Castables and precast shapes for grate-kiln pellet lines, where abrasion, alkali attack and ring formation limit campaign life.
View range →Lime and cement
Wear-resistant and chrome-corundum castables for lime kilns, and erosion-resistant grades for cement kilns and circulating fluidised-bed boilers.
View range →Ferroalloys and nickel
Composite brick-and-castable linings for RKEF ferro-nickel rotary kilns, plus silicon manganese and fluorspar for steel and alloy production.
View range →Aluminium casting
Non-wetting materials that resist metal penetration and corundum growth, and gas-refining systems that introduce inert gas into the melt.
View range →Coke making
Precast door-lining blocks that replace brick-by-brick door linings, with a stated service life of about five years against one to one and a half for standard brick.
View range →Industrial furnaces and boilers
General-purpose castables, insulation, burner blocks and heat-storage media for reheating furnaces, kilns and thermal equipment in metallurgy, building materials and power.

Graphite electrodes, HP Ø250 and UHP Ø400
Every product page carries the typical properties of each grade, so your engineers can compare before asking for a price.
| Property | HP Ø250High-power (HP) graphite electrode | UHP Ø400Ultra-high-power (UHP) graphite electrode |
|---|---|---|
| Resistivity (µΩ·m) | 5.8-6.6 | 4.8-5.8 |
| Modulus of rupture (MPa) | 10.0-13.0 | 10.0-14.0 |
| Young's modulus (GPa) | 8.0-12.0 | 9.0-13.0 |
| Bulk density (g/cm³) | 1.64-1.68 | 1.70-1.72 |
| Coefficient of thermal expansion (CTE) (10⁻⁶/°C)100-600°C | 1.1-1.4 | 1.1-1.4 |
How we work
From inquiry to shipment
A short, documented process. You always know which grade is being offered and on what terms.
Send your requirements
Furnace type, lining zone, operating temperature, current material and quantities. A drawing or an existing spec sheet is enough to start.
Grade selection
We match your conditions to grades from our range and send the data sheets for your engineers to review.
Quotation
Price, packing, delivery terms and lead time for the agreed grades and quantities, in writing.
Supply and documents
Goods are packed for export and shipped with commercial documents. Test certificates are supplied where available for the batch.
What to include in an inquiry
- Furnace or vessel type and the lining zone
- Operating temperature and atmosphere
- Material currently used and its service life
- Required quantity or annual consumption
- Destination port or delivery address
- Drawings or spec sheets, if available
