Congratulations on purchasing your AHL Corten Steel Grill—an outdoor cooking appliance renowned for its unmatched durability and distinctive aesthetic appeal. Unlike standard carbon steel or stainless steel grills, weathering steel grills require specific preparation steps to ensure safe operation, extend service life, and properly initiate the formation of a beautiful protective patina. This AHL Group guide provides a detailed step-by-step checklist for your weathering steel grill's first use. It covers the entire process from assembly and initial seasoning to ongoing maintenance, helping you enjoy years of reliable, high-performance grilling.
The Importance of Proper Initial Preparation
The success of your first barbecue and the lifespan of your Corten steel smoker or grill depend on proper initial setup. Skipping these steps may cause steel damage, food contamination, and shorten the equipment's expected lifespan.
Why Initial Preparation Extends Grill Lifespan
Residual oils, dust, and metal particles from manufacturing, if not thoroughly burned off during the first use, can bake into the weathering steel. This may cause uneven rust layer development or generate structural stress. Proper seasoning of the BBQ grill grates (distinct from the natural weathering steel rusting process) creates a non-stick surface, preventing rust corrosion in contact areas.
Safety Precautions for New Weathering Steel Grills
The initial heating cycle is critical for releasing residual manufacturing chemicals. Conducting the first grill session at a safe distance from buildings with adequate ventilation is a non-negotiable safety requirement.

Essential Preparation Steps
Please strictly follow these steps to prepare your AHL Corten BBQ grill for its first use.
Step 1: Unpacking and Assembly
Carefully follow the manufacturer's instructions
Gently remove all components from their packaging. Before assembly, wipe the weathering steel surface with a clean, damp cloth to remove any dust accumulated during transport. Assemble the unit on a flat, stable surface, ensuring all bolts and fasteners are securely tightened according to the AHL Group manual.
Step 2: Site Selection and Placement
Prioritize Dual Safety Considerations
Position your new Corten steel barbecue grill on a non-combustible surface (concrete, patio pavers, gravel). Due to high-temperature risks, maintain a minimum 10-foot (3-meter) clearance from buildings, overhanging branches, and flammable materials. Select a level, well-ventilated location.
Step 3: Initial Burning and Curing
This is the most critical step for removing manufacturing residues.
Removing Manufacturing Residues and Grease
► Fuel: Load your preferred fuel (charcoal or wood) onto the barbecue grill, but do not add any food.
► Ignition: Heat the grill to 300°F to 400°F (150°C to 200°C).
► Duration: Maintain this temperature for at least 1 to 2 hours. This process burns off protective coatings, grease, and residual paint, ensuring food remains uncontaminated. Smoke may be produced during this stage—this is normal.
Step 4: Cooking Surface Preparation
The weathering steel body does not require seasoning, but the cooking grate (typically stainless steel or cast iron) must be seasoned.
Grill Maintenance Guide
► Cleaning: After burn-in, allow the grill to cool slightly. Use a brush to remove ash and charcoal residue from the grates.
► Oil Application: Apply a thin, even layer of high-smoke-point cooking oil (such as canola, grapeseed, or flaxseed oil) to the grill surface using paper towels or a cloth.
► Baking: Reheat the grill to approximately 350°F (175°C) for 30–45 minutes until the oil polymerizes and bonds with the surface, forming a protective non-stick layer. For optimal results, repeat this seasoning process 2–3 times.
Step 5: Your First Cooking Experience
Start with Simple, Low-Risk Ingredients
For your first cook, choose simple, high-fat ingredients like fatty cuts of meat or hamburger patties. The fat helps further set the seasoning layer. Avoid delicate ingredients like fish or lean meats and vegetables, which are more prone to sticking during initial use. Enjoy your first meal on the AHL Corten charcoal grill!
Managing the Corten Patina Process
The heat generated by the grill will interact uniquely with the weathering steel body.
Expected Changes During Initial Heating
During the first few uses, high temperatures will accelerate the formation of the protective rust layer on the weathering steel far beyond what natural rain and air exposure would achieve. Areas near the firebox will develop a deeper, near-black patina, while outer regions will form a distinctive deep reddish-brown rust. This variation is normal and contributes to the Corten grill's unique character.
How High Temperatures Accelerate Rust Formation
Rapid thermal cycling induced by intense flames accelerates the natural oxidation process. Elevated temperatures hasten surface moisture evaporation, bringing rust-promoting elements to the surface. This accelerates the formation of a protective oxide layer, significantly enhancing the weathering steel's durability.
Controlling Rust Runoff and Stains
Like all weathering steel products, the grill will experience minor rust runoff during the first few weeks of outdoor use. To manage this, place a non-porous mat or tray beneath the grill to collect runoff, preventing stains on concrete or deck surfaces until the rust layer fully stabilizes.
Safety Protocols for New BBQ Grills
Fire Safety and Clearance Requirements
Always maintain the recommended 10-foot clearance from combustible materials. Never operate the grill under enclosed awnings or structures.
Proper Fuel Handling and Storage
When not in use, store charcoal, wood, or propane cylinders away from the grill. The use of any fuel accelerants is strictly prohibited except for dedicated charcoal lighters or fire starters.
Emergency Measures and Equipment
Keep a fire extinguisher (Class B or K, suitable for grease fires) or a large container of baking soda readily available near the grilling area for immediate response to fires or emergencies.
Maintenance from Day One
Investing in an AHL Corten barbecue grill means lower structural maintenance costs, but proper grill and ash management remains essential.
Initial Cleaning Procedure
After each use, scrape residue off the cooking grate with a grill brush. While the grate is still warm, reapply a thin layer of seasoning oil to prevent environmental moisture from corroding the steel.
Establish a Weekly Maintenance Routine
Empty the ash pan and clean the firebox weekly (or after several uses). Accumulated ash retains moisture and chemicals that may accelerate surface corrosion or damage the steel base.
Seasonal Maintenance Essentials
Before winter or extended storage, apply a thick layer of protective oil to the grill surface. Ensure the ash pan is empty, and the weathering steel body is thoroughly dry before covering with a breathable cover (if used), preventing moisture buildup.
Frequently Asked Questions About Corten Grill
Q: How Long Will My Grill Stop Smoking?
After the initial 1-2 hour burn-in period, the BBQ grill will no longer produce residue-related smoke. Any subsequent smoke will only originate from the cooking process or fuel combustion.
Q: Can I Cook Directly on the Weathering Steel Surface?
No. The cooking area of AHL weathering steel grills is designed for use with a separate seasoning grate. The weathering steel body requires the formation of a protective patina layer and must not come into direct contact with food.
Q: How Do I Best Control Temperature?
When using a Corten steel smoker or grill, achieve precise temperature control by adjusting the damper/vent. Regulate the fuel's oxygen supply—opening the vent increases flame intensity; closing it reduces flame and lowers temperature.
Conclusion: Experience the Joy of Grilling with Corten Steel Grills
The initial preparation you invest in your AHL Corten metal grill translates directly into decades of robust, low-maintenance performance. By completing the initial burn-in process, thoroughly seasoning the grill, and understanding the formation of the weathering steel patina, you ensure your grill fulfills its aesthetic and functional potential, becoming a durable cornerstone of your outdoor cooking adventures.
