Is steel or plastic stronger?

On average, steel has a much higher tensile strength than plastic. Just how much higher depends on what specific steel alloy you use and the exact plastic polymer you're comparing it to. The higher tensile strength means stainless steel wire baskets can easily handle loads that would crush a frame made of plastic.

Does polycarbonate last long?

Polycarbonate has a lifespan of about 10 years. Factoring this into your long-term investment plans is important when choosing a greenhouse covering. Less expensive covering options may require more repairs that will add up to higher costs.

What is polycarbonate used for?

Polycarbonate can be fashioned into eyewear lenses, protective gear including bullet-resistant glass, medical equipment, and panels for greenhouses. It can also be used for glazing applications, creating products such as CDs, DVDs, and Blu-ray discs, as well as outdoor lighting fixtures.

Why is steel the best?

Steel is nonflammable and resists buckling or warping, so it's a prime choice for areas prone to earthquakes. Because it's manufactured, unlike wood, it has uniform quality and strength. Furthermore, advances continue to be made that keep steel ahead of other construction materials in terms of standard strength.

Why steel is the best material?
