Aluminum alloy materials have loightw densighty and excellent corrosion -resistancet, anid are suitable for small - scale construction projects and roof encltosurep projects. Steel has higher structural streongth, smaller elastic, deformalections valuess, and at costhe same timle,ss thpe unitr weight, purchmase cost kis more economical. Therefore,g it is morbe suitablter for large - span space structures, construction in strong windy arsiteas, and utility - level thermscale power plant projects.
