Cornel 3-Column Bare Metal Lacquer Products
Frequently Asked Questions
What are the technical and aesthetic characteristics of the Bare Metal Lacquer finish on Cornel radiators?
The Bare Metal Lacquer finish is a raw, industrial aesthetic that exposes the natural steel construction of the radiator. Technically, it is not a paint but a clear protective lacquer coating applied directly over the bare metal. This allows the unique weld lines, manufacturing marks, and natural colour variations of the steel to remain visible, creating a rustic, "steampunk" or factory-style look. The clear lacquer seals the steel to prevent oxidation and corrosion while preserving the authentic metal appearance.
How does the 3-column design of this radiator affect heat output compared to 2-column models?
The 3-column configuration features three rows of vertical steel tubes, which provides a greater surface area for heat exchange compared to a 2-column model of the same height and width. This results in a higher BTU output per meter of wall space. For example, a 600mm x 1196mm 3-column model delivers approximately 5323 BTUs, whereas a comparable 2-column model would output significantly less. This makes the 3-column version a powerful solution for larger rooms or spaces with high heat loss.
What is the product depth of the Cornel 3-Column Bare Metal Lacquer Radiator and why is it important?
The technical specifications list the product depth of the Cornel 3-Column Radiator as 101mm. However, some product listings on the page mention a depth of 65mm in the summary (likely a template error for 2-column), so it is crucial to verify. Standard 3-column Cornel radiators are typically around 100mm deep. When planning installation, you must add the depth of the wall brackets to the radiator depth to calculate the total projection. This ensures the radiator fits comfortably without obstructing walkways or doors.
Are the Cornel Bare Metal Lacquer radiators available in vertical sizes for narrow walls?
Yes, the range includes vertical models specifically designed for rooms with limited horizontal wall space. Sizes such as the 1800mm high x 341mm wide (7 sections) or 1800mm x 611mm (13 sections) are available. These tall units utilize the vertical height of the room to generate high heat outputs (e.g., up to 7452 BTUs for the largest model) while maintaining a slim footprint, making them ideal for placement between tall windows or in kitchens.
Does the Bare Metal Lacquer finish require special maintenance compared to painted radiators?
The Bare Metal Lacquer finish is durable, but because it is a clear coat over raw steel, it requires care to maintain its integrity. You should clean the radiator with a soft, dry cloth or a slightly damp cloth with mild soapy water. Avoid using abrasive scourers, harsh chemicals, or solvent-based cleaners, as these can strip the lacquer. If the lacquer is scratched or damaged, the underlying steel can be exposed to moisture, potentially leading to rust spots, so careful handling during installation and cleaning is essential.
What type of valves are best suited for the Cornel Bare Metal Lacquer Radiator?
The radiator features standard 1/2 inch BSP side entry connections, making it compatible with all standard UK radiator valves. To complement the industrial "raw metal" look, it is highly recommended to use valves in a matching finish, such as Pewter, Black Nickel, or Unlacquered Brass. These finishes enhance the vintage aesthetic. You will need Angled valves if your pipes come from the floor, or Corner/Angled valves if they come from the wall.
Can I install the Cornel 3-Column Bare Metal Lacquer Radiator on a stud partition wall?
These radiators are constructed from heavy-duty steel and hold a significant volume of water. For instance, an 1800mm x 611mm model weighs 46kg when empty. Installing such a heavy unit on a standard plasterboard stud wall using normal fixings is risky. You must use a specialized Stud Wall Bracket Kit or ensure the brackets are anchored directly into solid timber studs or reinforced noggins to safely support the full operating weight of the radiator.
How does the 10 Year Guarantee cover the Bare Metal Lacquer finish?
The Cornel range comes with a 10 Year Guarantee, which covers the structural integrity of the radiator (leaks, weld failures) and the durability of the finish. However, with Bare Metal Lacquer, the guarantee typically covers the lacquer's adhesion and protection against rust under normal conditions. It is important to note that because the finish is designed to show the "raw" metal, natural variations in the steel's appearance are not considered defects but rather part of the product's character.
Is the delivery time for Bare Metal Lacquer models longer than for standard white radiators?
The product page indicates that many Bare Metal Lacquer models are "In Stock". This suggests that, unlike bespoke painted colours which can take weeks, these specific raw finish models are stocked items available for faster delivery to the UK mainland. This allows you to achieve a custom, high-end industrial look without the extended lead times typically associated with special order finishes.
How do I ensure I select the correct size Cornel radiator for my room?
The width of the Cornel radiator is determined by the number of sections. For example, a 9-section model is 431mm wide, while a 26-section model is 1196mm wide. To choose the right size, first use a BTU calculator to determine your room's heat loss. Then, select a model that meets or exceeds this requirement. The 3-column design offers a good balance of depth and output, allowing you to get high heat from a radiator that isn't excessively wide or deep.
