Baking Sheet

This is the aluminum hardening on the surface, the colour can effectively alter or change depending on the hardness of the water, and other factors. This is a natural process known as seasoning. This discolouration can be removed with vinegar or lemon juice, the discolouration does not impact the performance of the pans.
Aluminum prevents rusting by hardening up the surface, the colour can effectively alter or change depending on the hardness of the water, and other factors. This is a natural process known as seasoning. For the best results, we recommend using parchment paper.
Although yes, it can be used on a BBQ, it is not recommended as it would cause discoloration to the pan.
They are made in China under the direct supervision and quality control done by Crown Cookware. We do not manufacture stainless steel products in our factory as these baking sheets are a combination of aluminum and stainless steel.
They would not be for use on a gas stovetop. These baking trays are recommended for oven/toaster oven use only. As any accidental contact with the element on the stovetop would melt right through the metal.
The baking sheets comfortably withstand temperatures up to 700 Farenheight (370 Celcius) without any warping or loss of structural integrity.
The two smallest pans 6" x 10" and 9" x 13" are made of 20 gauge material. The larger half sheet pan, size 13" x 18", is 19 gauge. As you're aware, the lower the gauge, the more heavy-duty pan.
Our pans are made of natural, pure virgin non-toxic Aluminum and do not have any artificial coatings. We recommend greasing the sides and using parchment.
