hi, ironically, it's just called Drain Cover. just add Stainless Steel + "Washer" or "Washing" in your search.

On Lazada they have this brand RuYiYu that sells 3 types of feeders, but doesn't include the square sides. most drains here have the hinge thing on 1 side for opening & closing so i guess this type won't fit unless you get the frame.

On 11street they have this drain with frames but no rubber hose feeder:

And I saw 1 similar to what you posted Complete with feeder & frame in Homepro for around rm55+.

All 3 types mentioned has 3 layers, top cover, bottom slot & middle slot. i think the middle slots will reduce the opening for smoother flow but it's also possible depending on your washer, that the reduced opening might cause backsplash. But if that happens, i think you can just remove the middle parts and use the frame + top cover. as long you don't stand on it i think it should work. if you wash the floor, water can enter the drain normally without the middle parts.

One purpose for the middle part i think is for odorless.

but my question is how to remove the old drain including the frame as i believe they are cemented?

and how to install the new frame? since the original sides already have cement, won't adding new cement means the new frame might not level properly with the floor?

and finally you add silicone on the edges?

noob here never installed a drain cover b4.

the usual ones do you mean the white plastic ones?

mines already metal, but i want to change it so can fit washer drain. when they gouge, how to prevent the debris from falling into the drain and potentially clog the drain?
