Opening any Source VMT file for a game texture, the properties will usually have what type of surface prop to use so it reacts properly in the world when bullets or something else interacts with it (metal, grass, glass, snow, etc) via '$surfaceprop'.

Is there any way possible for SourceMod to detect this?

Some examples, find out what the player is standing on... or if a traceray was pointed at a "grass" texture ...or a bullet hit it...etc.

Example VMT

"lightmappedGeneric"
{
	"$basetexture"	"sometexturename"
        "$surfaceprop" 	"metal"
}

Thanks for any insight!

A bit of a late reply, but it is possible with SourceMod 1.10+ I believe.

float clpos[3];
float eyeang[3];
GetClientEyePosition(client, clpos);
GetClientEyeAngles(client, eyeang);
char surfname[128];
Handle trace = TR_TraceRayFilterEx(clpos, eyeang, MASK_SHOT, RayType_Infinite, TraceEntityFilter, client);
int surfflags = TR_GetSurfaceFlags(trace);
TR_GetSurfaceName(trace,surfname,sizeof(surfname));
int surfprops = TR_GetSurfaceProps(trace);
CloseHandle(trace);
PrintToChat(client,"TRMaterial Flags %i Props %i Name %s",surfflags,surfprops,surfname);

The SURF_ defines are in scripting\include\sdktools_trace.inc
Although I don't think it gives info like $surfaceprop, the $basetexture is in SurfaceName though. Maybe you can use the info in the flags and props or do a
if (StrContains(surfname,"metal",false) != -1)
