Design a modern and professional steel trading company catalog with a sleek layout. The color scheme should be predominantly dark blue, complemented by yellow accents and white backgrounds for a clean, minimalist feel. The catalog should feature sections like 'Finished Materials,' 'Raw Material,' 'Semi-Finished,' and 'Other Metals.' Each section should display clear, high-quality images of steel products such as sheet/plate, wire rod, rebar, billet, slab, copper cathode, zinc ingot, and others. The font should be bold and easy to read, with concise labels for each product image. Incorporate a subtle, professional background pattern, and ensure the overall design is clean, modern, and visually appealing.
