Ultimate FAQ Guide to Metal Ceiling Access Panels

What Metals Are Used For Ceiling Access Panels?

Ceiling access panels can be made from carbon steel, galvanized steel, stainless steel, and aluminum.

Metal ceiling access panel

炭素鋼は通常、ステンレス鋼よりも鈍いです。 

鉄と炭素のみで構成されているため、磁性があり、より展性があります。 

This steel is also prone to corrosion, so it is not recommended for ceiling access panels in harsh conditions, such as humid industrial sites.

ステンレス鋼は、鉄と炭素の合金にクロム、ニッケル、モリブデンを加えて作られます。 

It had several grade series that have different properties.

ステンレス鋼と亜鉛メッキ鋼

Steel grades 304 and 316 differ in the content of all these additives. 

Grade 316 is more resistant to salt and corrosion, whereas grade 304 is cheaper.

316Lや304Lもあります。 

グレード 316L と 304L は炭素含有量が低いため、強度が少し高くなります。 

しかし、市場ではあまり頻繁に使用されていません。 

亜鉛メッキ鋼 腐食を防ぐ亜鉛の保護層でコーティングされています。 

このタイプの鋼はステンレス鋼よりも高価で重いです。 

Another type of steel that can be used is cold-rolled steel, which is thinner and more dense than normal steel—and thus, it is stronger.

NEMA 4 enclosures use 18-10 ゲージ鋼, which is about 1-4 mm thick.

エンクロージャはアルミニウム合金で作ることもできます。 

これらは必ずしも鋼合金より優れているわけではありませんが、目的やニーズによっては優れている場合もあります。 

Just like steel grades, aluminum alloys can be either of the 5052 or the 6061 series. 

アルミニウムとステンレス鋼

どちらも軽量ですが、5052 は溶接性に優れ、6061 は耐腐食性に優れています。 

また、6061 の方が高価です。

アルミニウムの表面には腐食を防ぐ酸化物の層があります。 

This material is especially good for places exposed to solvents, petrochemicals, some acids, most sulfates and nitrates.

What Shapes Of Metal Ceiling Access Panels Are There?

What Frames Can Metal Ceiling Access Panels Have?

Metal ceiling access panels can have concealed frames, recessed flange frames, flush frames. 

Concealed frames and recessed flange frames are pretty much the same.

Concealed frames are similar, but they do not have flanges, yet the frame is invisible.
