Harga Kepingan Keluli Corten

Corten steel sheets are generally more expensive than ordinary carbon steel sheets because they contain alloying elements such as copper, kromium, dan nikel. Unsur-unsur ini meningkatkan rintangan kakisan atmosfera dan membenarkan keluli membentuk lapisan karat pelindung. Atas sebab ini, keluli corten sering digunakan dalam struktur luar, panel seni bina, dan produk landskap.

Berbanding dengan kepingan keluli karbon standard, keluli corten biasanya dianggap a keluli khusus jarak pertengahan. Ia tidak semahal keluli tahan karat, tetapi ia biasanya berharga lebih tinggi daripada plat karbon tergelek panas biasa.

Perbandingan Harga: Keluli Corten lwn Keluli Karbon

Perbezaan kos terutamanya datang daripada komposisi aloi dan piawaian pengeluaran.

Untuk ketebalan dan saiz yang sama, kepingan keluli corten selalunya 15% kepada 40% lebih mahal daripada kepingan keluli karbon standard.

Perbezaan Harga Biasa mengikut Ketebalan

The price gap changes with thickness because thin sheets are more affected by processing cost.

Secara amnya, the thicker the material, the smaller the relative price gap.

Why Corten Steel Costs More

The higher price of corten steel comes from several factors.

1. Unsur Aloi

Corten steel contains additional alloy elements that ordinary carbon steel does not have in significant amounts:

• Tembaga (Cu)
• Chromium (Cr)
• nikel (Dalam)
• Fosforus (P)

These elements improve corrosion resistance and increase production cost.

2. Lower Production Volume

Ordinary carbon steel is one of the most widely produced steel products in the world. Corten steel has a smaller market volume and is mainly used for specialized applications such as:

• Pelapisan seni bina
• Panel taman
• Bekas
• Jambatan
• Arca luar

Because production quantity is lower, the cost per ton is usually higher.

3. Pemprosesan Permukaan

Many corten steel sheets are sold with additional processing such as:

• Pre-rusted finish
• Pemotongan laser
• Decorative perforation
• Fabrikasi tersuai

These extra processes can further increase the total cost compared with plain carbon steel sheets.

Is Corten Steel Considered Expensive?

Whether corten steel is expensive depends on what material it is compared with.

Compared with Carbon Steel

ya, corten steel is more expensive than ordinary carbon steel.

Compared with Stainless Steel

Tidak, corten steel is usually much less expensive than stainless steel.

A simple comparison:

This means corten is often chosen when users want better outdoor durability without paying the higher cost of stainless steel.

Why Buyers Still Choose Corten Steel

Even though corten steel sheets cost more than carbon steel, banyak projek masih memilihnya kerana faedah jangka panjang.

Kelebihan utama

• Tiada lukisan diperlukan untuk banyak aplikasi luaran
• Penampilan karat hiasan semula jadi
• Kos penyelenggaraan yang lebih rendah
• Hayat perkhidmatan luar yang lebih lama
• Kekuatan struktur yang baik

Untuk produk taman, corten selalunya boleh menjimatkan kos penamat kerana lapisan karat menjadi permukaan hiasan akhir.

Corten lwn Carbon Steel untuk Projek Taman

Kedua-dua bahan boleh digunakan untuk produk landskap, tetapi prestasi mereka berbeza.

Keluli karbon biasa biasanya memerlukan pengecatan atau galvanizing untuk kegunaan luar, manakala corten boleh dipasang sebagai keluli kosong dan cuaca secara semula jadi dari semasa ke semasa.
