Aluminium is the usual choice for most baking, because it conducts heat quickly and browns evenly. Stainless steel is chosen for hygiene, durability and non-reactivity, but it conducts heat less well. Aluminised steel sits between the two: a steel core for rigidity with an aluminium-based surface layer. This guide compares the three materials for restaurants, bakeries, caterers and food manufacturers in Singapore. It covers heat behaviour, wear, care, food safety and the effect on oven energy use.
TL;DR
- Aluminium heats and cools quickly, which suits cakes, cookies, bread and pastry where even browning matters.
- Stainless steel is durable, easy to clean and non-reactive, but it takes longer to heat and is a weaker heat conductor on its own.
- Aluminised steel adds rigidity to an aluminium-type surface. Its coating must stay intact, so damaged pans should be replaced.
- Lighter, lower-mass trays reduce the amount of metal an oven must heat, which supports lower energy use.
- Choose by task: aluminium for baking performance, stainless steel for acidic, wet or heavy-wash work, aluminised steel for rigid trays in daily rotation.

Quick comparison of the three materials
The table summarises the practical differences. The sections below explain each row.
| Criterion | Aluminium | Aluminised steel | Stainless steel |
|---|---|---|---|
| Heat conduction | Excellent, fast response | Good, driven by the surface layer and steel core | Lower than aluminium unless it has an aluminium core |
| Heat retention | Cools quickly after removal | Moderate | Retains heat longer |
| Browning | Even, predictable | Even when the coating is intact | Can be uneven on plain stainless |
| Reaction with acidic food | Bare aluminium can react over long contact | Exposed steel can oxidise if the layer is damaged | Non-reactive |
| Rigidity | Lighter, can bend under heavy loads | Rigid | Rigid and durable |
| Cleaning | Hand washing is usually preferred for bare aluminium | Avoid abrasive scouring | Easy to clean |
| Typical use | Cakes, cookies, bread, pastry | High-volume trays, bread and roasting | Wet preparation, acidic recipes, holding and serving |
How aluminium behaves in the oven
Aluminium is an excellent heat conductor. Baking-sheet testing published by The Spruce Eats reports that aluminium heats and cools quickly, while steel sheets take longer to heat but retain heat. In a commercial kitchen this has two practical effects.
First, uncoated aluminium responds quickly to changes in oven temperature. Pans heat evenly, so batches brown consistently from the centre of the tray to the edges.
Second, aluminium cools quickly once removed from the oven. This reduces carry-over baking, where the product keeps cooking on a hot tray after leaving the oven. For delicate items such as sponges, shortbread and cookies, this protects texture and colour.
Colour matters as well. The same testing reports that light-coloured sheets generally bake cookies more efficiently than darker ones. Darker bakeware can brown the edges and bottoms faster, so staff may need to check products earlier or lower the oven temperature slightly.
Where aluminium is weaker
Aluminium is lighter than steel and can bend if it is stacked heavily, dropped or loaded with dense product. Bare aluminium can also react during long contact with highly acidic foods such as tomato or citrus-based mixtures. For those recipes, use a pan with a non-reactive surface or a stainless steel alternative. Aluminium also discolours with repeated machine washing, which affects appearance but not baking performance.
How stainless steel behaves
Stainless steel is valued for being easy to clean and non-reactive. It does not interact with acidic ingredients, and it tolerates heavy washing routines. These are real advantages in a kitchen with high turnover and strict hygiene routines.
The trade-off is heat transfer. Stainless steel conducts heat less well than aluminium, so plain stainless pans can heat unevenly. Browning may vary across the tray, with hot spots near the edges. The heat it takes on is also held longer, which can overbake delicate products left on the tray.
For this reason, stainless steel suits tasks where gentle, even heat is less critical:
- Roasting vegetables, meat and seafood.
- Wet or acidic preparation, such as marinated items and sauces.
- Holding, transferring and serving hot food.
- Water baths and steaming.
Some stainless pans have an aluminium or copper core bonded inside. These combine the cleaning advantages of stainless steel with better heat spread. Check the specification when buying.
What aluminised steel is
Aluminised steel is steel that has been coated with aluminium or an aluminium-silicon alloy, usually by hot dipping. The steel core supplies strength. The coating improves resistance to corrosion and heat. If the coating is damaged and the steel is exposed, oxidation can start at that point.
For a bakery, this makes aluminised steel a practical middle option:
- It is rigid, so large sheet pans, bun trays and loaf tins keep their shape in daily use and in heavy rotation.
- It heats more quickly than plain stainless steel, because the surface behaves like aluminium.
- It is generally priced and handled like standard commercial bakeware, though suppliers set their own prices.
The condition of the surface decides its lifespan. Avoid steel wool and aggressive scouring, and retire any pan where bare metal is visible.
Which material suits which task
No single material is best for everything. Match the pan to the product.
Cakes, sponges and pastry
Cakes need quick, steady heat. Light-coloured aluminium is the usual recommendation for layer cakes, because it spreads heat evenly and cools quickly after removal. Dark or heavy pans can over-brown the edges before the centre sets.
Cookies and biscuits
Use light-coloured, uncoated aluminium sheets where possible. They heat and cool quickly, so cookies colour evenly and stop cooking soon after leaving the oven. Stainless steel trays can produce uneven browning without an aluminium core.
Bread and buns
High-volume bread production benefits from rigid trays that do not warp across repeated cycles. Aluminised steel and heavier aluminium are both common here. Steel holds heat well, which supports crust development.
Roasting, savoury and acidic dishes
Stainless steel is the safer choice for acidic marinades, tomato-based dishes and long contact with wet ingredients, because it does not react with the food.
Non-metal alternatives
Silicone is sometimes used for moulds and portioned items. For a comparison with metal, see our guide to silicone vs metal bakeware.
Wear, warping and care
Durability depends on thickness, construction and handling more than on the material name alone.
- Prevent warping. Avoid placing very hot pans under cold water. Rapid temperature change distorts thin metal. Let trays cool before washing.
- Match cleaning to the material. Stainless steel tolerates vigorous cleaning. Bare aluminium and aluminised surfaces are better washed with a soft sponge and mild detergent.
- Do not store wet. Moisture trapped between stacked pans encourages staining and, on damaged steel, corrosion.
- Retire damaged pans. Pans with bare steel showing, deep gouges or lifted coatings should be replaced.
- Rotate pans. Using the same pans in sequence gives even wear and consistent results across batches.
Food safety and coatings
Uncoated aluminium is widely used for baking, but it can react with strongly acidic ingredients. Where a recipe is acidic and the product will sit in the pan for a long time, use stainless steel or a lined pan, or transfer the food to another container.
Non-stick coatings need separate attention. The Singapore Food Agency advises that non-stick pans with a damaged coating should not be used. It recommends replacement when the coating shows excessive scratches, peeling, flaking or chipping, because food may be contaminated by PFAS and micro- and nanoplastics. This applies to coated aluminium and coated aluminised steel pans alike. Use soft utensils on coated pans, and remove them from service when the surface starts to deteriorate.
Coating chemistry is also an active research topic. An academic case study on bakery mould coatings identifies concerns about PFAS release from PTFE coatings and evaluates alternatives for safety, functionality and sustainability. Businesses that want to reduce reliance on non-stick surfaces can use plain aluminium with baking paper or release agents, or stainless steel for suitable tasks.
Bakeware, oven energy use and workflow in Singapore
The choice of tray affects energy use. Singapore’s National Environment Agency publishes a best practice guide on energy efficiency for food manufacturers. It states that efficiency can be improved by selecting ovens by operating efficiency and by minimising the thermal mass of internal accessories such as trays and baskets. In plain terms, an oven that heats heavy, unnecessary trays spends energy warming metal instead of food.
Practical steps for a bakery or central kitchen:
- Use the lightest tray that holds its shape. Thick, heavy pans carry more thermal mass. Choose a gauge suited to the load rather than the heaviest available.
- Remove idle trays. Do not leave empty racks and spare pans in the oven during preheating or between batches.
- Standardise sizes. Pans that match the oven rack and trolley dimensions reduce handling time and wasted oven space.
- Buy durable items. The same NEA guidance points to durable, professional-grade items that reduce replacement cycles and are easy to clean to sanitary standards.
For more on reducing oven consumption, see our articles on commercial oven energy consumption and low-cost oven fixes for Singapore bakeries.
How to choose: a short decision guide
- List the products. Group them as delicate (cakes, cookies, pastry), structural (bread, buns) and savoury or acidic (roasts, marinades).
- Assign materials. Light aluminium for the delicate group, aluminised steel or heavier aluminium for the structural group, stainless steel for the savoury or acidic group.
- Check the oven. Convection ovens and combi ovens heat trays differently. Confirm tray size and rack spacing before ordering.
- Decide on coating. Plain surfaces avoid coating replacement. Coated pans need a schedule for inspection and replacement.
- Plan the cleaning method. Match pan material to the dishwashing process in the kitchen.
- Buy in standard sizes. This keeps replacement simple and rotation even.
Our perspective on bakeware and energy
We see bakeware as part of the oven system, not a separate purchase. A kitchen that upgrades its oven for energy efficiency but keeps heavy, mismatched or warped trays loses part of the benefit.
Our approach is to start from the products a business bakes, then match the oven and the trays to them. Light aluminium suits delicate products. Rigid aluminised steel suits high-volume trays. Stainless steel suits the work where non-reactivity and cleaning come first.
The same logic applies to energy. Our energy-efficient equipment is designed to help food businesses lower electricity costs, and eligible purchases may qualify for government grants. We advise customers on this when they choose equipment, so that tray choice, oven choice and the grant application are considered together.

FAQ
Is aluminised steel better than aluminium for baking?
Neither is better in every case. Aluminium conducts heat more quickly and suits delicate products. Aluminised steel is more rigid and holds its shape in busy kitchens. Its surface layer must stay intact, so replace pans where the steel is exposed.
Is stainless steel or aluminium better for baking sheets?
For most baking, aluminium is the stronger choice, because it heats and cools quickly and browns evenly. Stainless steel suits roasting, acidic foods and heavy washing, as it is non-reactive and easy to clean. Stainless pans with an aluminium core combine some of both benefits.
Is aluminium bakeware safe?
Uncoated aluminium is widely used, but it can react with strongly acidic ingredients over long contact. For those recipes, use stainless steel or a pan with a non-reactive surface. For coated pans, the Singapore Food Agency advises replacing any pan with a scratched, peeling or flaking coating.
Do dark pans bake differently from light pans?
Yes. Darker bakeware can brown the edges and bottoms faster, so products may need earlier checking or a slightly lower oven temperature. Light-coloured sheets generally bake cookies more efficiently.
Does bakeware affect oven energy use?
It can. Singapore’s National Environment Agency guidance recommends minimising the thermal mass of trays and baskets in ovens. Using lighter trays that suit the load, and removing unused trays during preheating, reduces the metal an oven must heat.
