Heat-Resistant Steel Cover Manufacturer | Custom Furnace Protective Cover | FH® Alloy

Heat-Resistant Steel Cover for Industrial Furnaces
Custom High-Temperature Protective Cover | OEM Manufacturing | FH® Alloy

FH® Alloy manufactures heat-resistant steel covers for industrial furnaces, heat treatment equipment, and other high-temperature applications. These covers are designed to provide thermal protection, structural shielding, and reliable service performance in demanding furnace environments.

Based on different equipment structures and working conditions, the cover can be manufactured with customized diameter, height, wall thickness, opening dimensions, mounting holes, reinforcing structure, and material grade.

We support drawing-based manufacturing, sample-based production, and replacement fabrication for overseas customers.

Product Overview
A heat-resistant steel cover is commonly used as a protective outer shell, furnace internal cover, thermal shielding component, or high-temperature enclosure in industrial heating systems.

This type of component is typically designed to:

• Protect internal parts from direct high-temperature exposure
• Isolate certain areas within furnace systems
• Improve structural stability
• Support thermal insulation design
• Adapt to specific equipment installation requirements
• Provide a customized enclosure for high-temperature operation

As shown in this product, the structure can include:

• Cylindrical shell body
• End plate with central opening
• Mounting or positioning holes
• Reinforcing tabs or brackets
• Customized connection interfaces

Drawing Reference
OD = Outside Diameter
ID = Inside Diameter
T = Wall Thickness
H / L = Height or Length
All dimensions can be manufactured according to customer drawings, samples, or measured data.

Structural Design
This type of cover can be designed with different structural details depending on the application.

Available design options may include:

• Closed or partially closed cylindrical body
• Central opening design
• Multi-hole mounting face
• Reinforcing ribs or support tabs
• Welded bracket structure
• Special cut-outs or inspection holes
• Machined installation surface
• Combined material construction

The final design should match the customer's furnace system and installation method.
